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.

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).

If any of the input is low then AND gate 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.

Logically, 1 or high is associated with true in positive logic. Hence if all inputs are true/high/1 then output is true/high/1.
Electrically, 1 or high is associated with +5v in TTL. When switches are in series and all are closed then only high input is available( can be applied) at output.

Output of AND gates are high when all the inputs are 1. If any of the input is 0, the output will be 0.

The output of an AND gate only high when all its inputs are high otherwise it is low.

The AND gate gives high output when all the inputs to the gate are high.
