(a)
Interpretation:
Whether the given transformation requires hydroxyl to protect it is to be determined.
Concept introduction:
The protecting groups are used to make the specific functional group temporarily unreactive in a poly-functional group molecule under reaction conditions needed to make modifications in other functional group in the molecule. The protecting group can be removed once the desired reaction is carried out and restores the original functional group.
