The correct answer is A. active voice.
When the subject performs a particular action, it means that the sentence is active rather than passive. If the object was the focus of the sentence, then it would be a passive sentence.
For example: I love reading books - active sentence
Books are written by writers - passive sentence
These sentences can be in future, past, or present tense - which means that tense is not important.

I did 25 (students) x 7 = 175 (students)
So then I did 18 x 7 = 126
so the answer is C) 126 students.
But if your teacher or whoever wants to know how to do it correctly and show the work correctly then don't do what I did because they may take off points (if they're strict...) (and that probably didn't make any sense but whatever...) Hoped this helped! :)
