Kalyan,
It depends on the entire sentence. One is in active voice and another is in passive voice. Active voice almost always prefered except in sentences which explain a theory or such, where the doer(subject) is not as important as the act itself.
MGMAT SC book talks about this. and has a few examples.

Also the voice of the rest of the sentence dictates the voice of the choices.

HT helps

which one is active or which one is passive
