Answer 1

The Correct Option is A

Step 1: Understanding disaccharides.
A disaccharide is a carbohydrate composed of two monosaccharide units. Sucrose is the most common disaccharide, consisting of glucose and fructose.
Step 2: Explanation of other options.
- Glucose is a monosaccharide (simple sugar), not a disaccharide. - Fructose is also a monosaccharide, not a disaccharide. - Starch is a polysaccharide composed of many glucose units, hence not a disaccharide.
