When raisins ( Kismis ) are placed in water , they swell due to the process of

Options

A. diffusion
B. guttation
C. imbibition
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why raisins (kismis) swell when placed in water. We need to identify the process responsible for this phenomenon.

2. **Identifying the Processes**: The options given are:
- A) Diffusion
- B) Goutation
- C) Imbibition
- D) None of these

3. **Explaining Imbibition**: Imbibition is a specific type of absorption where water is absorbed by solids, particularly colloids, leading to an increase in volume. Raisins are dried fruits that contain a significant amount of solid material.

4. **Applying Imbibition to Raisins**: When raisins are placed in water, they absorb the water due to imbibition. The solid structure of the raisins allows them to take in water, causing them to swell.

5. **Conclusion**: Therefore, the swelling of raisins in water is due to the process of imbibition. The correct answer is option C.
