Which choice best combines the two sentences into one grammatically correct sentence?
A. The scientists worked to develop a new type of artificial muscle, which would be able to contract and expand with greater speed and strength than any natural muscle.
B. The scientists worked to develop a new type of artificial muscle, and this artificial muscle would be able to contract and expand with greater speed and strength than any natural muscle.
C. The scientists worked to develop a new type of artificial muscle; this artificial muscle would be able to contract and expand with greater speed and strength than any natural muscle.
D. The scientists worked to develop a new type of artificial muscle, it would be able to contract and expand with greater speed and strength than any natural muscle.

Correct Answer is: A

Choice A correctly combines the two sentences using a relative clause. The relative pronoun "which" refers to the artificial muscle, creating a grammatically correct and cohesive sentence. The other choices create run-on sentences, comma splices, or incorrect pronoun use.
