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
For manufacturing-process identification:
\begin{itemize}
\item Match the material first (wood, metal, plastic),
\item Prefer hand-tool operations for traditional artifacts,
\item Eliminate modern industrial processes when not applicable.
\end{itemize}
Step 1: Observe the artifact carefully. It is a carved wooden peacock with:
\begin{itemize}
\item Numerous small circular holes,
\item Smooth curved contours,
\item Fine surface finish and detailing.
\end{itemize}
\bigskip
Step 2: Identify operations that are relevant to traditional woodcraft:
\begin{itemize}
\item Drilling: Required to create the repeated circular perforations.
\item Chiselling: Used to carve the peacock form and feather details.
\item Sanding: Needed to smoothen surfaces after carving and drilling.
\item Finishing: Applied to enhance appearance and protect the wood.
\end{itemize}
\bigskip
Step 3: Eliminate incorrect operations:
\begin{itemize}
\item \emph{Milling}, \emph{powder coating}, and \emph{punching} are industrial processes and not relevant to traditional wooden artifacts.
\end{itemize}
\bigskip
Step 4: Among the options, only Option D lists operations that are all relevant to making the artifact using traditional methods.
