Correct answer: D

Correct sequence: Fetch → Decode → Execute.

  1. Fetch: The CPU reads the next instruction from memory into the instruction register.

  2. Decode: The instruction is interpreted and the control signals are prepared.

  3. Execute: The CPU performs the operation specified by the instruction.

Therefore, the choice that lists Fetch − Decode − Execute is the correct answer.
