As the bus lines on memory chips of computers have become thinner and the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive have vastly increased.
(A) the chips’ circuits are 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 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 has
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have

Alright, I'll give it a shot
B is right.
(A) "are" doesn't need to be there, it's excessive. "Power" applies to the chips and the devices. The Correlative Conjuction of "both" is correct. Both..And. "both the power of the chips and of the electronic devices would be okay. "have" is plural and "power" singular.
(B) fixes "are" and moves "both" after "power," eliminating the need for OF before "the electronic devices" changes "have" to "has"
(C) same as B except it doesn't fix the parrellism
(D) pronoun error. Does their refer to bus lines, memory chips, or computers?
Ritesh,
I think E is wrong because of change in meaning from original sentence. The difference between B & E is:
B: the power of both X and Y
E: both power of X and Y
B means that the 'power of X and the power of Y are going up'. However E means that the 'power of X is going up and Y is going up'. Since in this context Y = electronic devices, E would need to have "the number of" before Y to make more sense.

My thoughts - please let me know if you disagree.

I agree with your explanation but don't we need "have" because of the "power of both X and Y"?
A - No need of a verb "ARE", since the verb in the second compound clause is ellipted. The verb of second is "have become".
C, need a plural verb "have" instead of "has"
D and E have pronoun problems. THEIR has no clear referent.
