Rennet is employed in :

Options

A. Bread making
B. Fermentation
C. Cheese making
D. Synthesis of antibiotics

Answer

**Step-by-Step Solution:**

1. **Understanding Rennet**: Rennet is a complex set of enzymes that is primarily used in the dairy industry. It is derived from the stomachs of ruminant animals, such as cattle.

2. **Identifying the Main Component**: The chief component of rennet is chymosin, which plays a crucial role in the coagulation process of milk.

3. **Function of Chymosin**: Chymosin helps in the curdling of casein, which is the main protein found in milk. This curdling process is essential for cheese production.

4. **Analyzing the Options**: The question provides four options:
- Bread making
- Fermentation
- Cheese making
- Synthesis of antibiotics

5. **Determining the Correct Option**: Among the given options, cheese making is the only process that involves the curdling of milk proteins (casein) using rennet. The other processes (bread making, fermentation, and synthesis of antibiotics) do not involve rennet.

6. **Conclusion**: Therefore, the correct answer is that rennet is employed in cheese making.

**Final Answer**: Cheese making (Option 3).
