answer is given as c. @akriti

Answer 1

There is an little dot at enable

In many of made easy test is equivalent to not gate

So enable=0 all entries in k map is zero

Hence in pos form it will be

$\prod$M(0,1,2,3,4,5,6,7)

Hence option C

Comments

enable input is zero .all the entries in kmap will be zero. C seems correct.
