  • A Whenever 0 is present at input
  • B Only when all input =0
  • C Whenever 1 is present at input
  • D Only when all input =1.
Correct Answer: Option C
Explanation:
The NOR gate is a digital logic gate that implements logical NOR - it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results.
