Brutal#007!

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

is it B?
parallelism should be maintained both X and Y- i.e both the power of chips and ''the power of '' electronic devices

IMO B

C & D - out - unnecessary "are more complex"
E - out - "Their" is ambiguous, it should be chips' circuits
As the power has increased not the electonic devices hence A is out

Testing point: SVA, ||ism

Both X and Y (X n Y have to be parallel) ~> A, E out

C n D r out b/c of S-V agreement rule

B remains
