Washing the rice many times using a large amount of water before cooking leads to

Options

A. loss of vitamin E
B. loss of surface protein
C. loss of vitamin-B
D. loss of water soluble carbohydrates

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the effects of washing rice multiple times with a large amount of water before cooking.

2. **Identifying Nutrients in Rice**: Rice contains various nutrients, including vitamins and carbohydrates. The focus here is on water-soluble vitamins, particularly vitamin B and vitamin C.

3. **Effect of Washing on Water-Soluble Vitamins**: When rice is washed repeatedly, the water-soluble vitamins (such as vitamin B and C) can leach out into the water. This means that the more you wash the rice, the more of these vitamins are lost.

4. **Considering Other Nutrients**: The question also mentions vitamin E and surface proteins. Vitamin E is fat-soluble and not lost through washing, and proteins are generally not water-soluble, so they are also not lost through washing.

5. **Conclusion**: Therefore, washing rice many times using a large amount of water primarily leads to the loss of water-soluble vitamins, specifically vitamin B and C.

6. **Final Answer**: The correct answer is the loss of vitamin B (and also vitamin C).
