1.	Assertion: `NAND` or `NOR` gates are called digital building blocks. Reason: The repeated use of `NAND` (or `NOR`) gates can produce all the basic or complicated gates.A. If both the assertion and reason are true and reason is a true explantion of the assertion.B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.C. If the assertion is true but reason falseD. If both the assertion and reason are false.
Answer» Correct Answer - A These gates are called digital building blocks because using these gates only (either `NAND` or `NOR` ) we can compile all other gates also (like `OR,AND,NOT,XOR`).
