Detailed Solution

Aldehyde bisulphite and ketone bisulphite are well-crystallized, water-soluble compounds that are generated when aldehydes and ketones interact with sodium bisulphite.

A cyanohydrin is generated when cyanide is added to an aldehyde or ketone. The need for a basic catalyst in cyanohydrin production is an essential characteristic. Since hydrogen cyanide is a weak acid by nature, the best results come from activating it by forming the cyanide ion, which can operate as a carbon nucleophile, in the presence of a small quantity of a strong base.

Therefore, the correct option is option B [Both (A) and (R) are true and (R) is not the correct explanation of (A)].
