The circuit shown in the given figure is a

Correct answer: Full subtractor

The circuit has three inputs, A, B, and C, and two outputs, D and E. The figure shows the lower AND gate receiving B and C, so its output is BC.

• Difference output: The lower XOR gate gives B ⊕ C, and the top XOR gate gives D = A ⊕ (B ⊕ C) = A ⊕ B ⊕ C.

• Borrow output: The upper AND gate gives A'(B ⊕ C), and the lower AND gate gives BC. The OR gate combines them as E = A'(B ⊕ C) + BC.

• Full-subtractor form: A'(B ⊕ C) + BC is equivalent to A'B + A'C + BC, the standard borrow-out expression of a full subtractor.

Final answer: Full subtractor.
