Best answer
The correct answer is (b) Overflow

The best I can explain: If the number of bits in the sum exceeds the number of bits in each added numbers, it results in overflow and is also known as excess-one. In case of any arithmetic operation, if the result has less number of bits than the operands, then it is known as underflow condition.
