If A, B, C and D are the inputs to the circuit below what is its output? A B C D Select one: (A · B) + (C + D) (A + B) · (C · D) (A · B) + (C + D) (A + B) · (C · D)

A logic circuit has three inputs, A, B and C. It generates an output of 1 only when A = 0, B = 1, C = 0 or when A = 1, B = 1, C = 0. Design a combinational circuit for this system.
