Show answer & explanation
Correct answer: D
Correct matching: the correct correspondence between the items is listed below with brief justifications.
Controlled inverter: a circuit that transmits a binary word or its 1's complement. A controlled inverter conditionally inverts the bits of a word under control, producing either the original word or its 1's complement.
Full adder: a circuit that can add 3 bits. A Full adder combines two operand bits and a carry-in to produce a sum and carry-out.
Half adder: a logic circuit that adds 2 bits. A Half adder produces a sum and carry for two input bits but has no carry-in input.
Binary adder: a circuit that can add two binary numbers. Binary adders perform multi-bit addition, typically by cascading single-bit adders.
