ADecode, store, fetch

BExecute, fetch, store

CFetch, decode, execute

DStore, execute, decode

Step-by-Step Solution

Solution:

Step 1: Recall the CPU instruction cycle steps
The CPU follows a cycle: it first fetches the instruction, then decodes it, and finally executes it.
Step 2: Check the order of steps
Only Fetch, decode, execute lists the steps in the correct order: fetch, decode, execute.
Final Answer:
Fetch, decode, execute -> Option C
Quick Check:
Instruction cycle = fetch -> decode -> execute [OK]

Quick Trick: Remember: Fetch before decode, then execute [OK]
