Explanation:
A serial binary adder processes binary addition one bit at a time, sequentially propagating the carry from one stage to the next. Here’s why Option 1 is correct:
Characteristic of Serial Adders:
Sequential Carry Propagation: Each full adder (FA) must wait for the carry-out from the previous FA before computing its sum and carry.
Example: To compute bit *i*, the adder needs the carry generated from bit i−1.
Operates Bit-by-Bit: Unlike parallel adders, serial adders do not process all bits simultaneously.
