Correct option is D
A full adder is a digital circuit that adds three 1-bit binary inputs:
1 Two main bits: A and B (the bits to be added).
2 Carry-in bit: Cin (from the previous stage, if applicable).
The output of a full adder consists of:
· Sum (S): The result of adding the three input bits.
· Carry-out (Cout): The carry resulting from the addition, which can be passed to the next stage in multi-bit addition.
Thus, a single full adder can handle the addition of 3 bits at a time.
