In the 4 × 1 multiplexer, the output F is given by F = A ⊕ B. Find required inputs I₃I₂I₁I₀.

1. 1010
2. 0110
3. 1000
4. 1110

Correct Option: B

We know that,
for 4 × 1 MUX
F = A.B.I₀ + AB.I₁ + A.B.I₂ + A.B.I₃
But required output
F = A ⊕ B = AB + AB
Therefore I₀ = I₃ = 0
I₁ = I₂ = 1
Required I/P
I₃ I₂ I₁ I₀ = 0110
