Answer 1

Correct Answer is 3.( three inputs and two outputs)

A full adder circuit requires three inputs and two outputs. The three inputs are typically denoted as A, B, and Cin (carry-in), and the two outputs are Sum and Cout (carry-out). The full adder circuit adds the three inputs (A, B, and Cin) to produce the sum (Sum) and carry-out (Cout) results.
