Smart answer::
Output of and gate is high when all the inputs of the and gate is high.

Bcoz in AND GATE Y=A*B then we multiply in AND GATE and we know that to obtain output high.We should give inputs high i,e A=1 B=1 and C=1.

If all the inputs are high output is high. Other wise low.

Table for AND gate
A B Y
0 0 0
0 1 0
1 0 0
1 1 1
Output is high only when both the inputs are high.

For AND gate if A, B, C are three inputs than it's output is given by A.B.C .
So output of AND gate will obtain high only when A=1, B=1, C=1.
Because in electronic high means 1 and 1 will obtain if all of three input will high (1).
If any one input will be 0 (low) then output will be low (0).
That's why answer in which A=B=C=1 is correct.

When there all the inputs of an AND gate are 1 or HIGH then the output will be HIGH or 1.

And is gate which multiply all the inputs so all inputs should be high to get o/p as high.
