The figure below shows a circuit composed of four logic gates. The final output of this circuit is false.
Which of the following is a true statement about input B?
Input B must be true in order for the final output to be false.
Input B must be false in order for the final output to be false.
Input B can be either true or false and the final output will always be false.
Regardless of the value of B, there is no way that the final output can be false.
