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

Table for AND gate

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.
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).

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

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.

When the all input of AND gate are high or 1, then the output will 1 or high.

The output of an AND gate is high (1) only if all the inputs are high (1). The output is low (0) if any one of the input is low (0). The reason is AND gate performs multiplication function.

When all input are high then output is high.

There are three input present and all have high value =1.
So in in and operation 1*1*1=1.
It is a high.
So in in and operation 1*1*1=1.
It is a high.
