A full adder can subtract three bits of data
A
TRUE
B
FALSE
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The full adder is used to add three 1-bit binary numbers A, B, and carry C. The full adder has three input states and two output states i.e., sum and carry.

Detailed explanation-2: -A full adder circuit is central to most digital circuits that perform addition or subtraction. It is so called because it adds together two binary digits, plus a carry-in digit to produce a sum and carry-out digit. It therefore has three inputs and two outputs.

Detailed explanation-3: -A full subtractor is a combinational circuit that performs subtraction involving three bits, namely A (minuend), B (subtrahend), and Bin (borrow-in) . It accepts three inputs: A (minuend), B (subtrahend) and a Bin (borrow bit) and it produces two outputs: D (difference) and Bout (borrow out).

Detailed explanation-4: -Again the combinational circuit that performs addition of three bits (Two significant bits and a previos carry) is called Full adder.
