Question

Solution

Correct option is The circuit is a combination of AND and NOT gates. The output of the NAND gate is connected to the input of a NOT gate. The combined circuit is called a NAND gate. The Boolean expression for the NAND operation is Which that the output X is just the negation of the output of the AND operation.
