Answer:A
Which of following are known as universal gates?
A. NAND & NOR B. AND & OR C. XOR & OR D. EX-NOR & XOR
Explanation: The NAND & NOR gates are known as universal gates because any digital circuit can be realized completely by using either of these two gates, and also they can generate the 3 basic gates AND, OR and NOT.
