Could you please explain, why the option C is wrong?

C is wrong because of two reasons:

1. The subject "the power of the chips AND the electronic devices they drive " is plural, whereas the verb "has" is singular.

2. "the chips’ circuits are more complex"..... the verb "are" is wrong, should be "have become". In Option B (OA), this correct verb is used, but omitted (correctly) to avoid repitition in parallel items.
The placement of BOTH is also awkward in This construction.

Can you please give some insights into use of if and whether

"If" requires a condition. "Whether" depicts a choice between two options.

I do not know if I will go... wrong. (no condition - a case of choice between two options)
I do not know whether I will go... correct.

I don't know the OA but here is my reasoning...

A. the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have
INCORRECT...Meaning is illogical.The eletronic devices havn't vastly increased...!!
B. the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has
CORRECT... the chips’ circuits [have become] more complex, the power of (both the chips and the electronic devices)they drive has
C. the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has
INCORRECT... both the power... and the electronic devices require plural verb
D. their circuits are more complex, the power of both the chips and the electronic devices they drive have
INCORRECT... Their creates ambiguity
E. their circuits more complex, both the power of the chips and the electronic devices they drive have
INCORRECT... Same as D

OA is missing. Please provide OA.

OA has been added. The explanation above by sleepynut is good - moreover, C and D can be eliminated because of the usage of "are"; E is wrong because of the same reason as that A is wrong as stated in the explanation.

A. the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have

B. the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has

C. the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has

D. their circuits are more complex, the power of both the chips and the electronic devices they drive have

E. their circuits more complex, both the power of the chips and the electronic devices they drive have

Both the power is wrong and the power of both is the correct usage and convey the correct intended meaning.

the Power is singular 'has' should be used to represent singular.

(A) the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have -- Parallelism -illogical meaning in both the power of the chips and the electronic devices they drive
(B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has -- Correct
(C) the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has - same as A ; subject-verb agreement issue
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have - subject-verb agreement issue -- the power is singular and thus needs has verb
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have -- Parallelism -illogical meaning same as A

[quote="bmwhype2"]As the etched lines on computer memory chips have become thinner and the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have vastly increased.

(A) the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have.. Both X and Y X= power and Y electronic devices does not make sense
(B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has- Correct use of Both X and Y chips and electronic device
(C) the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has- Same error as A
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have SV error power .. have
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have- Same error as A[/quote]

Wonderful question to test subject verb agreement .
"Power" is the subject of the second sentence so we have to use has .
Based on this we can eliminate A , D and C
Now between B and E their in E is ambiguous we need have proper nun here B is more clear also it suggests that the power of the chips increases so did electronic device this not what it wants to convey

As the etched lines on computer memory chips have become thinner and the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have vastly increased.
A. the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have
B. the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has
C. the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has
D. their circuits are more complex, the power of both the chips and the electronic devices they drive have
E. their circuits more complex, both the power of the chips and the electronic devices they drive have

When I scan this vertically I see 2 splits basically one at the beginning (the chips' and their circuits) and other at the end (has and have).
If I go by the split in the beginning I feel skeptical about "their" as its antecedent is ambiguous, but to eliminate this something else may also be of some use.
See the middle and find the subject "both the power of the chips and the electronic devices". This is fishy what should it be "both the power of the chips and the electronic devices" or "the power of both the chips and the electronic devices".
Undoubtably the later one.
Hence A and C go OUT.
Hence "the power" becomes the subject and the verb with it would be "has" hence D and E go out.
B is a clear Winner.
