A wooden artifact made using traditional tools and processes is shown below. Which option shows the relevant operations involved in its making, not necessarily in the actual production sequence?
Show Hint

Step 1: List woodworking steps. A carved wooden peacock needs drilling, chiselling, finishing and sanding. Step 2: Reject non-wood processes. Milling and powder coating do not apply to traditional woodwork. \[ \boxed{\text{Option 4}} \]
