This question was addressed to me in final exam.

Enquiry is from Magnitude Comparator in chapter Combinational Circuits of Digital Circuits

Answer 1

Right choice is (a) Only one output terminal

The best I can explain: An Identity Comparator is a digital comparator that has only one output terminal for when A = B either “HIGH”  A = B = 1 or “LOW”  A = B = 0.
