Step 1: Understand the goal.
The goal is to assess the internal quality of an egg to determine if it is suitable for storage.
Step 2: Evaluate the given options.
Candling: This is a process where a bright light is shone through an egg to view its internal contents. It allows inspectors to check the size of the air cell, the condition of the yolk and white, and the presence of any defects like blood spots or cracks. This is a primary method for quality assessment.
Washing: This cleans the exterior of the egg but does not assess internal quality.
Oiling/Waxing: These are methods used to seal the pores of the eggshell to prolong shelf life after quality has been determined. They are preservation techniques, not selection techniques.
\end{itemize}
Therefore, candling is the correct process for selecting good quality eggs.
