None of the above

Detailed explanation-1: -As indicated by the truth table, the purpose of an Exclusive-NOR gate is to output a “high” (1) logic level whenever both inputs are at the same logic levels (either 00 or 11).
Detailed explanation-2: -The output of EX-NOR gate is 1 when both the inputs are 1 (high) and if both the inputs are 0 (low).
Detailed explanation-3: -The output level of the XNOR gate is high only when both of its inputs are the same, either 0 or 1. The symbol of the XNOR gate is the same as XOR, only complement sign is added. Sometimes, the XNOR gate is also called the Equivalence gate.
Detailed explanation-4: -The output of an AND gate is HIGH only when all inputs are HIGH. The output of a NAND gate is HIGH whenever one or more inputs are LOW. The output of a NOR gate is LOW whenever one or more inputs are HIGH.
