  1. A combinational circuit has input A, B, and C and its K-map is as shown below. The output of the circuit is given by—
    1. (AB + AB) C
    2. (AB + A B) C
    3. A B C
    4. A ⊕ B ⊕ C
Correct Option: D


A BC + A B C + A B C + ABC
= C (A B + AB) + B C (A B + AB)
= C ( AB + AB) + C (AB + AB)
= A ⊕ B ⊕ C
