Why are NAND and NOR gates called universal gates?

A Because they are the most commonly used gates in computers

B Because any digital circuit can be built using only NAND gates or only NOR gates

C Because they process both binary and decimal data

D Because they have the highest output voltage

Explanation

NAND and NOR are called universal gates because any digital circuit — including AND OR and NOT gates — can be constructed using only NAND gates or only NOR gates.
