A 4 × 1 multiplexer with two selector lines is used to realize a Boolean function F having four Boolean variables X, Y, Z and W as shown below. S0 and S1 denote the least significant bit (LSB) and most significant bit (MSB) of the selector lines of the multiplexer respectively. I0, I1, I2, I3 are the input lines of the multiplexer. The canonical sum of product representation of F is

A

F (X, Y, Z, W) = Σ m(0 , 1, 3, 14, 15)

B

F (X, Y, Z, W) = Σ m( 0, 1, 3,11,14)

C

F (X, Y, Z, W) = Σ m( 2, 5, 9, 11, 14)

D

F (X, Y, Z, W) = Σ m(1,3,7,9,15)
