In a typical execution cycle, which one of the following sequences accurately depicts the steps involved?
- Instruction decode → Instruction fetch -> Operand fetch → Execute → Result store
- Instruction fetch → Instruction decode → Operand fetch → Execute → Result store
- Operand fetch → Instruction fetch → Instruction decode → Execute → Result store
- Instruction fetch → Operand fetch → Instruction decode → Execute → Result store (correct)
