Sucrose is present in:
Correct answer: A. Sugar cane
- A. Sugar cane
- B. Milk
- C. Almonds
- D. None of these
Explanation
Sucrose is a disaccharide composed of glucose and fructose, commonly found in sugar cane and sugar beet. Sugar cane is cultivated extensively for its sap, which is processed to extract sucrose, making it a primary source of table sugar. Milk, on the other hand, contains lactose, not sucrose, as its main sugar. Almonds do not naturally contain sucrose; they are a source of proteins, healthy fats, and other nutrients. Therefore, the correct answer is sugar cane, as it is directly associated with sucrose production.
