In which operation carry is obtained?
A
Subtraction
B
Addition
C
Multiplication
D
Both addition and subtraction
Explanation: 

Detailed explanation-1: -3. In which operation carry is obtained? Explanation: In addition, carry is obtained. For example: 1 0 1 + 1 1 1 = 1 0 0; in this example carry is obtained after 1st addition (i.e. 1 + 1 = 1 0).

Detailed explanation-2: -Full Adder is the adder which adds three inputs and produces two outputs. The first two inputs are A and B and the third input is an input carry as C-IN. The output carry is designated as C-OUT and the normal output is designated as S which is SUM.

Detailed explanation-3: -In case full adder construction, we can actually make a carry in input in the circuitry and could add it with other two inputs A and B. So, in the case of Full Adder Circuit we have three inputs A, B and Carry In and we will get final output SUM and Carry out. So, A + B + CARRY IN = SUM and CARRY OUT.

Detailed explanation-4: -So, In parts of the processor, adders are used to calculate addresses, table indices, increment and decrement operators, etc.
