Question

Solution

Correct option is

NAND and NOR gates

The OR or the AND or the NOT gates alone cannot give a different gate by repeated use, i.e., two or-more OR or AND or NOT gates do not yield a new gate. But the repeated use of NAND (or NOR) gates can give all other gates like OR, AND and NOT. Hence the NAND (or the NOR) gate serves as a building block in digital circuits.
