When both the inputs of OR gate are high then also output of NOR gate is high. So we cannot say that only in case of both low it will be high.

The output of NOR gate is high only when all the inputs given to the gate are low that means the output will be 1 only when all inputs are 0.

By the truth table at 0 0 input output is 1 and remaining all are 0. Therefore the high output is the 1.
Therefore, the ans is option : A.
Therefore, the ans is option : A.

NOR gate have two or more i/p and only one o/p , AND gate have also two or more i/p and one o/p and NOT gate have 2 i/p or 1 o/p.

NOR means compliment of or for a 3 input or gate it has 7 possibilities of high.
Hence the ans is 1
Hence the ans is 1

SO
A B C Y
0 0 0 0
0 0 1 1

The output of a NOR gate is high only when all the input will be in low (0) state

When A=0, B=0, C=0 then OR gate output is LOW then NOR gate output is HIGH.

If all input is 1 then it is high, if all inputs are zero then it is low.
