Innovative companies are not only skillful in developing new products but also in finding new ways to promote old ones.
(A) are not only skillful in developing new products but also in finding
(B) are skillful not only in developing new products but also in finding
(C) not only are skillful in developing new products, they also find
(D) not only develop new products, but they are also skillful in finding
(E) are both skillful in the development of new products and in finding
Correct answer: B
The correct structure is "are skillful not only in developing new products but also in finding." This applies the "are skillful" both to "developing new products" and to "in finding."
A: Skillful needs to come before "not only."
B: Correct
C: Lacks the correct idiomatic structure "not only ... but also." Also, if "are skillful" comes after "not only," then it needs to be repeated before "in finding."
D: Not parallel ("develop ... in finding") and changes the meaning (not indicating that innovative companies "are skillful" in developing new products).
E: Not parallel ("in the development ... and in finding").
