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.

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

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.

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.

If any of the input is low then AND gate output is low.

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.
