Correct answer: D
In total there are 16 input combination that can be created using 4 input lines, into a 4*1 multiplexer. Instead of trying out all of them one by one, we can take advantage of options and eliminate the wrong option.
So, with option D, we get. I0 = 0, I1=1,I2=1,I3=1,
f = A’B’(0) + A’B(1) + AB’(1) + AB(1)
f = A’B + A = A+B
