Output equation for the two input(A,B) exclusive-NOR gate is (A.B)+(A bar.B bar)...
substitute input values...

We know that in ex-nor gate same input is 1 and different input is 0. So clearly c is a right answer.

In ex-nor gate if both terminal high or low then it gives high output other wise it gives low out put.

For exclusive-nor if both the inputs are same then only the output is 1.

It is very appreciable and building opinions of different experts.

I am very happy to get the chance of getting their little bit part of knowledge through this link.
