Which main component fetches, decodes, and executes instructions in sequence?

Answer and explanation

Correct answer: Central Processing Unit

The governing concept is the CPU instruction cycle: fetch, decode, and execute. The Central Processing Unit obtains an instruction from memory, interprets what operation is required, and carries it out, using components such as the control unit and ALU. A monitor displays output, a scanner captures input, and a printer produces hard copy. Thus option A is correct.
