Correct option is A
The given symbol is NOR gate symbol.
The NOR gate is a digital logic gate that outputs true or high (1) only when both inputs are false or Iow (0). If any of the inputs are true, the output will be false. The truth table for a NOR gate with two inputs, A and B, is as follows:
Explanation:
· When both A and B are 0 , the output is 1 .
· When A is 0 and B is 1 , the output is 0 .
· When A is 1 and B is 0 , the output is 0 .
· When both A and B are 1 , the output is 0 .
