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
key A
