Official Solution

Correct Option: (2)

To determine which logic gate is represented by the given combination of logic gates, let's analyze the operation of a NAND gate: The NAND gate is a combination of an AND gate followed by a NOT gate. Its output is true (1) unless both inputs are true (1). In terms of a truth table: Input A Input B AND Output NAND Output 0001010110011110 The truth table demonstrates that the NAND gate produces an output of false (0) only when both inputs are true (1), characteristic of its operation. This confirms the given logic gate is the NAND gate.
