The following Variable Entered Map (VEM) represents which of the following function:
f(A, B, C, D) = ∑(1, 2, 3, 4, 7, 8, 9, 14, 15) + Φ(3, 5, 12, 13)
f(A, B, C, D) = ∑(1, 2, 4, 8, 10, 8, 13, 15) + Φ(3, 6, 12, 14)
f(A, B, C, D) = ∑(1, 2, 4, 7, 8, 10, 13, 15) + Φ(6, 12, 13)
f(A, B, C, D) = ∑(1, 2, 4, 7, 8, 9, 12, 13) + Φ(3, 5, 14, 15)
Answer: Option
Explanation:

f(A, B, C, D) = A B C [D(0) + D(1)] + A B C[D(1) + D(f)]

+ A BC[D(0) + D(1)] + A BC[D(0) + D(1)] + AB C[D(1) + D(1)]

+ AB C[D(0) + D(0)] + ABC[D(1) + D(1)] + ABC[D(Φ) + D(Φ)]

= ∑(1, 2, 4, 7, 8, 9, 12, 13) + Φ(3, 5, 14, 15).
