Ex-OR and Ex-NOR Gates

Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function.

Using A as the control, when A = 0, X is the same as B. When A = 1, X is the same as B.

Using A as the control, when A = 0, X is the same as B. When A = 1, X is the inverse of B.

Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the same as B.

Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the inverse of B.
