Multiple choice

What will be the value of three inputs A, B and C of OR gate, when output obtained is low?

  1. A = 0, B = 0, C = 0

  2. A = 1, B = 0, C = 1

  3. A = 0, B = 0, C = 1

  4. A = 1, B = 0, C = 0

  5. A = 1, B = 1, C = 1

A Correct answer
Explanation

If A = 0, B = 0, C = 0 then A*B*C = 0*0*0 = 0 (since OR gate performs addition).
