The output of an AND gate is high (1) only when all the inputs are high, even if anyone of the input is low (0) then the output will be low (0).

A B C -> A. B.C
1 1 1 -> 1.
So, the right answer is option C.
1 1 1 -> 1.
So, the right answer is option C.

And gate.
A B Y
0 0 0
0 1 0
1 0 0
1 1 1.
The output is high only when both the inputs are high.
A B Y
0 0 0
0 1 0
1 0 0
1 1 1.
The output is high only when both the inputs are high.

In AND gate any 2 IP are high op is high.

The Logic of and gate is when all the 3 inputs are high output is high when any one input is low output is low.

Output of an AND gate is high when all inputs are high a=1, b=1, c=1.

IF,
A=0,B=0,C=0 - 0
A=1,B=0,C=0 - 0
A=0,B=1, C=0 -0
A=1,B=1,C=0 - 0
A=1,B=0, C=1 -0
ONLY,
A=1,B=1,C=1 - 1(HIGH) BECAUSE A*B*C.
A=0,B=0,C=0 - 0
A=1,B=0,C=0 - 0
A=0,B=1, C=0 -0
A=1,B=1,C=0 - 0
A=1,B=0, C=1 -0
ONLY,
A=1,B=1,C=1 - 1(HIGH) BECAUSE A*B*C.
