The number of full and half-adders required to add 16-bit numbers is
Correct Answer: B
Question 37 Explanation:

But for rest of bits we need full address since carry from previous addition has to be included into the addition operation.
So, in total 1 half adder and 15 full adders are required.

8 half-adders, 8 full-adders
1 half-adder, 15 full-adders
16 half-adders, 0 full-adders
