Sentence Correction

Now that so much data travels via light-i.e., is carried in glass fibers rather than by electrical current-one goal of semiconductor research is to develop a silicon chip that can transmit and receive light signals directly, a development that may one day lead to smaller, faster semiconductors.

(A) to develop a silicon chip that can transmit and receive light signals directly, a development that may one day lead

(B) to develop a silicon chip with the capability of transmitting and receiving light signals directly, which may one day lead

(C) the development of a silicon chip that has the capability of transmitting and receiving light signals directly, a development maybe one day leading

(D) developing a silicon chip that can transmit and receive light signals directly, which may one day lead

(E) developing a silicon chip with the ability to transmit and receive light signals directly, with this development maybe one day leading

Is the OA [spoiler]{A}?[/spoiler]

A appears to be the correct answer.
In B & D 'which' points to 'light signals'; so they are wrong.
In E the clause(with this...) is erroneous.
In C there is a missing 'that' in the clause which makes A better than C.
(also 'leading to' in C sounds erroneous).


Any further suggestions are welcome.
