Out of the following gates, identify the gates which will give an output as '0' (zero) for the given inputs.

Options

  1. A(A) and (C)
  2. B(B) and (D)
  3. C(B) and (C)
  4. D(A) and (D)

Correct answer

A. (A) and (C)

Step-by-step solution

NAND Gate (A): With inputs A = 1 , B = 1 , the AND operation yields 1 , and its inversion gives output 0 . NOR Gate (B): Inputs A = 0 , B = 0 produce an OR output of 0 , inverted to yield 1 . AND Gate (C): Inputs A = 1 , B = 0 result in output 0 , as AND requires both inputs to be 1 . XOR Gate (D): For inputs A = 0 , B = 1 , which differ, output is 1 . Gates (A) and (C) both yield output 0 .
