GATE | GATE CS 2019 | Question 41

Consider three 4-variable functions f1, f2 and f3, which are expressed in sum-of-minterms
f1 = σ(0, 2, 5, 8, 14)
f2 = σ(2, 3, 6, 8, 14, 15)
f3 = σ(2, 7, 11, 14)
For the following circuit with one AND gate and one XOR gate, the output function f canbe expressed as:

(A) σ(7, 8, 11)
(B) σ( 2, 14)
(C) σ( 0, 2, 3, 5, 6, 7, 8, 11, 14)
(D) σ(2, 7, 8, 11, 14)
