Solution

The correct option is C 1,2-ethanediol and 2-chlorocychlohexanone
Ketone on reacting with alcohols gives ketals. When these ketals are treated with mineral acids it gives back the alcohol and ketone.

Here, the cyclic ketal is hydrolysis with acid to give its respective dihydric alcohol and the ketone.

Hence, option (c) is correct.
