Options

A. Solubilisation of food
B. Enjoying the taste of food
C. Decreasing surface area of food
D. Increasing surface area of food

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Chewing:**
Chewing is a mechanical process that occurs in the mouth when we eat food. It involves the action of our teeth grinding and breaking down food into smaller pieces.

2. **Identifying the Purpose of Chewing:**
The primary purpose of chewing is to prepare food for further digestion. By breaking down food into smaller particles, it makes it easier for enzymes to act on the food later in the digestive process.

3. **Analyzing the Options:**
- **Option A: Solubilization of food** - While chewing does help in mixing food with saliva, it is not primarily for solubilization.
- **Option B: Enjoying the taste of food** - Chewing does help in tasting food, but this is not its main function.
- **Option C: Decreasing surface area of food** - This is incorrect, as chewing actually increases the surface area.
- **Option D: Increasing surface area of food** - This is the correct answer, as breaking food into smaller pieces increases the surface area available for digestive enzymes.

4. **Conclusion:**
After analyzing all the options, the correct answer to the question "Chewing is required for" is **Option D: increasing surface area of food**.
