Which sequence correctly represents instruction execution in a computer?

Correct answer: Fetch, then Decode, then Execute

The governing concept is the CPU instruction cycle. First, the control unit fetches the next instruction from memory; second, it decodes the instruction to determine the required operation and operands; third, the CPU executes it through the appropriate unit. Therefore, option A gives the correct Fetch–Decode–Execute sequence. The other choices either place stages in the wrong order or include printing, scanning, storing, or deleting, which are not the standard three stages.
