Which logic gate is used to generate the Sum output of a half-adder?

Options

  • A. AND gate
  • B. OR gate
  • C. XOR gate
  • D. NOR gate
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

C. XOR gate

Detailed Explanation

Correct Answer: (C) XOR gate
The Sum output of a half-adder is generated using an XOR gate.
Sum = A ⊕ B
The XOR output is 1 when the two inputs are different.
