A NOR gate has 3 inputs A, B, C. For which combination of inputs is output HIGH

Question: A NOR gate has 3 inputs A, B, C. For which combination of inputs is output HIGH
[A].

A = B = C = 0

[B].

A = B = C = 1

[C].

A = B = 1 and C = 0

[D].

A = C = 1 and B = 0

Answer: Option A

Explanation:

NOR gate gives High output when all inputs are Low.
