For the logic circuit shown below the input Y is—

1. A ⊕ B
2. A ⊕ B
3. A ⊙ B ⊙ C
4. A ⊕ B ⊕ C

Correct Option: C

By using K-map, Y = Σ m (0, 3, 5, 6) → from given

Y = A B C + AB C + A BC + A B C
Y = C (A B + AB) + C (AB + B A)
Y = A ⊙ B + CA ⊕ B)
Y = C A ⊙ B + CA ⊕ B
{ ∵ A ⊙ B = A ⊙ B)
Y = A ⊙ B ⊙ C
Hence alternative (C) is the correct choice.
