Given N marices each of dimention A*B, filled only with 0 or 1.

What is the minimum number of cells you need to check so that you can differentiate between the N matrices?

The answer is log_base_2(N). Can someone explain this answer?

I'm not sure I understand the question, but

Suppose AB> N, Suppose N matrices, each having 1 zero and AB-1 ones. You'll need to see all O(N) position where zero is possible to differentiate matricies.
