Answer»

The correct answer is (a) 0

To explain: A comparator is a COMBINATIONAL circuit that TAKES two numbers as input in binary form and results whether one input is greater, LESSER or equal to the other input. In a digital comparator, only 3 outputs are possible (i.e. A = B, A >B, A < B). Other than this, the output will be 0.
