Very good discussion, Thanks for it.

Since we are applying logic'0' to NOT gate the input to the AND gate should be logic '1'right.
So, here now all the inputs are logic '1' so, how s=0?

It is basically an AND gate which has one of its inputs negated by an inverter. The input which is negated acts to inhibit the gate. Or we can say the gate will behave like an AND gate only when the negated input is set at a logic level '0'. Now we will see this through the circuit symbol and truth table for a four input INHIBIT gate.

Inhibit input is just as the third input to AND gate which is given through not gate as an input so,
When inputs are :- A * B * S(bar) = 1 * 1 *0 (bar).
Then output will be 1.
When inputs are :- A * B * S(bar) = 1 * 1 *0 (bar).
Then output will be 1.

Is inhibit is the opposite of enable?

When a digital "on" signal is present at a particular input (known as the inhibit input) to the logic circuit, the logical output from the logic circuit is blocked; and when the inhibit input signal is absent, the logical output from the logic circuit is affected only by signals at the remaining inputs.
Thus the answer is B.
Thus the answer is B.
