Correct:
A
Explanation
The correct answer is Option 1 (A-3, B-1, C-4, D-2). This matching is based on the biological and botanical sources of various carbohydrates.
- Cellulose (A-3): Cotton wool is almost pure cellulose (about 90%). It is a structural polysaccharide found in plant cell walls.
- Fructose (B-1): Known as "fruit sugar," fructose is the primary sugar found in honey, contributing to its intense sweetness.
- Maltose (C-4): Maltose, or malt sugar, is a disaccharide produced during the enzymatic breakdown of starch by amylase. Therefore, starch is its primary precursor/source in this context.
- Sucrose (D-2): Common table sugar is commercially extracted from sugarcane and sugar beets, where it serves as a major storage carbohydrate.
Options 2, 3, and 4 are incorrect because they mismatch these fundamental biochemical relationships, such as incorrectly linking sucrose to cotton or fructose to starch.
