Read the sentence. a decision was reached by scientists about when the experiment would begin. which revision changes the sentence so that it uses the active voice? before the experiment by scientists, a decision was reached. scientists reached a decision about when to begin the experiment. a decision was reached with scientists about beginning the experiment. the beginning of the experiment is a decision that was reached by scientists

The correct option would be the second one: Scientists reached a decision about when to begin the experiment.

In ACTIVE VOICE, the "doer" of the action is also the subject of the clause. In the sentence "[a] decision was reached by scientists about when the experiment would begin", the "doers" of the action are "scientists" and the action is "reaching a decision". So the clause "scientists reached a decision (...)" is in active voice.
