Consider the following multiplexer where 10, 11, 12, 13 are four data input lines selected by two address line combinations A1A0 = 00, 01, 10, 11 respectively and f is the output of the multiplexer. EN is the enable input. The function f(x, y, z) implemented by the circuit is :

• A. xyz'
• B. xy + z
• C. x + z
• D. None of these
