Directions: In this question, A statement of Assertion (A) is followed...
Explanation:
Deoxyribose is a monosaccharide, which is a type of carbohydrate. It is a component of DNA and is involved in the structure and function of nucleic acids. Therefore, the statement in Assertion (A) is incorrect.

Now let's analyze the Reason (R) given in the question.

Carbohydrates:
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen in the ratio of 1:2:1. They are one of the major macromolecules and play a crucial role in various biological processes. Carbohydrates include monosaccharides, disaccharides, and polysaccharides.

Optically Active:
Optical activity refers to the ability of a substance to rotate the plane of polarized light. Carbohydrates are optically active because they have chiral centers, which means they have four different groups attached to a carbon atom.

Polyhydroxy Aldehyde or Polyhydroxy Ketone:
Carbohydrates can be classified as either aldoses or ketoses based on the presence of an aldehyde or ketone functional group. Aldoses have an aldehyde group (CHO) and ketoses have a ketone group (C=O).

Substances that Give Aldehyde or Ketone on Hydrolysis:
Hydrolysis is a chemical reaction in which a compound is broken down by water. Some carbohydrates can be hydrolyzed to yield aldehyde or ketone compounds. For example, glucose, a monosaccharide, can be hydrolyzed to yield glucose-6-phosphate, which is an aldehyde.

Conclusion:
Based on the given Reason, carbohydrates are optically active polyhydroxy aldehyde or polyhydroxy ketone or substances that give aldehyde or ketone on hydrolysis. Since deoxyribose is a carbohydrate and does not meet the criteria mentioned in the Reason, the statement in Assertion (A) is false. Therefore, the correct answer is option (d) - A is false and R is true.
