This question is harder for me to understand than it would be to solve. I think B. 120 VAC is correct because the meter deflection would be just past mid range which is probably the most accurate portion of the scale. It wouldn`t be A. that would yield no meter deflection. C. would yield full scale deflection and maybe a little less accurate than B. D. is for DC measurements and should not be considered for AC measurements. I may have misunderstood the question and my answer and explanations may be all wet.

Some multimeters have capacitive inputs and only read AC. Some are directly coupled and will read DC also.
So you have to figure out which you have. That's easy. Try reading DC on the AC scale.
If it reads DC, then, A. and B. will be read correctly. C. and D. Will read the RMS value of the DC.

The multimeter will read zero if you're not measuring anything, but it depends on what you're measuring. Maybe you only posted part of the question. Your sentence doesn't make sense.

that does not make sense, try doing your own homework
