(A) the chipsâ€™ circuits more complex, both the power of the chips and the electronic devices they drive have - - - unneccesry insertion of "CHIP'S"(B) the chipsâ€™ circuits more complex, the power of both the chips and the electronic devices they drive has - - - uses HAS must use HAVE, as it is plural.
(C) the chipsâ€™ circuits are more complex, both the power of the chips and the electronic devices they drive has - - - HAS is wrong
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have - - - Sounds like 2 chips , as it reads, BOTH THE CHIPS.
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have - Satisifies, HAVE (plural), adn the use of BOTH

Correct me, if my explaination is wrong

the answer is B. Here power is the subject and so it must have "has". In E, "their" is ambiguous because it is not clear whether it is the etched lines or the chips.

"their" has no clear referent so (D) and (E) is out.

it is the "power" of "both chips and devices these chips derive" "has" increased, hence (A) and (C) is out.
