A full-adder adds _____ bits, and producing a SUM and a _____ A. 8, SUBTRACTION B. 3, CARRY C. 16, DIVIDE D. All of the above E. None of the above

The correct answer is: B. 3, CARRY

A full adder is a digital logic gate that performs addition on two binary numbers. It has three inputs: two binary numbers and a carry bit. It produces two outputs: a sum bit and a carry bit.

The sum bit is the result of adding the two binary numbers. The carry bit is a 1 if the sum of the two binary numbers is greater than 1.

A full adder can be used to add any number of binary numbers. It is a basic building block of many digital circuits, such as adders, subtractors, and multipliers.

The other options are incorrect because:

• A full adder does not add 8 bits. It adds 3 bits.
• A full adder does not perform subtraction. It performs addition.
• A full adder does not divide. It performs addition.
