Identify the Gates from 1 & 0 Inputs: Output (a) 0, (b) 1

[uzair_ha91]

Inputs of a gate are 1 & 0. Identify the gate if its output is
(a)0
(b)1
Attempt:
(a) And Gate but NOR and XNOR gates also match the description
(b)OR GATE alongwith NAND and XOR
So is writing down all the gates matching the requirements of the question (technically) correct?

It's a pretty bad question, but I suppose your answer is the best possible answer. You cannot uniquely identify the gate if you only know one line of its truth table.
