Shouldn't the answer be zero?

The answer they gave (A) is for the full-wave rectified.

Looks like they only calculated the average value for half of a period for the sine wave. If they calculated the value for second half of the wave, then they would have come up with zero.

Bad thing is this seems like just another error in the CI exams. Good thing is you know enough to catch them!!

its asking for magnitude, not avg of v(t)

 

[BamaBino]

It's asking for the "average magnitude" of the voltage v(t).
