Best answer 0 votes 0 votes C is the correct option. when one input of XOR is tied to 1 it works as inverter and it works like buffer when one input is tied to 0. truth table for XOR gate is A B F 0 0 0 0 1 1 1 0 1 1 1 0 you can cross check the answer from the table . Starting two rows where A is tied to 1 and gives the answer same as B. and in next two rows where A is 1 gives the answer as B'.

0 votes 0 votes let X be one input and 1 be the other input for 2input XOR gate. we have y = A'B + AB' ( where A and B are inputs to XOR ) y = X'.1 + X.0 = X' (Inverter when input is 1) if other input is 0, y = X'.0 + X.1 = X( Buffer) Hence C is correct answer.
