An adder in which the bits of the operands are added one after another is

A Half-adder
B Full-adder
C Serial adder
D All of the above
E None of the above

Correct Answer: Serial adder

Serial adder is a sequential circuit. Parallel adder is a combinational circuit. In serial adder, propagation delay is less. In parallel adder, propagation delay is present from input carry to output carry. Number of required full adder is fixed i.e. one.
