Answer is option D. Please draw k-map of three variables having 8 boxes. AB on one side and C on another side. AB varies 00, 01, 10, 11 and C varies 0, 1. Put values acc to table given of Y=1 in 0, 1, 6 and 7 number box.
AB changes from 00 to 10 so discard A because it changes from 0 to 1. Keep B bar because it remains same. In another side C changes from 0 to 1, so discard it also.
The answer is bar B because it has no change in it.

For this, the process is too long.
So by substituting those values in options you will get the answer.
