Solution

The correct option is D Both Assertion and Reason are incorrect
2-Deoxyribose $C_{5} H_{10} O_{4}$ is a carbohydrate. It is a monosaccharide.

It is a deoxy sugar, derived from the sugar ribose by loss of an oxygen atom.

Carbohydrates are optically active polyhydroxy aldehydes or polyhydroxy ketones or the compounds that can be hydrolysed to polyhydroxy aldehydes or polyhydroxy ketones.
Some carbohydrates like Rhamnose do not follow the formula $C_{x} (H_{2} O)_{y}$

Both Assertion and Reason are incorrect.
