Consider three 4-variable functions f1, f2, and f3, which are expressed in sum-of-min terms asf1 = ∑ (0, 2, 5, 8, 14), f2 = ∑ (2, 3, 6, 8, 14, 15), f3 = ∑ (2, 7, 11, 14)For the following circuit with one AND gate and one XOR gate, the output function f can be expressed as:

A. ∑ (7, 8, 11)
B. ∑ (2, 7, 8, 11, 14)
C. ∑ (2, 14)
D. ∑ (0, 2, 3, 5, 6, 7, 8, 11, 14, 15)
Answer» B. ∑ (2, 7, 8, 11, 14)
