Fruits And Vegetables Preservation

Step 1: Understanding the preservation method.
Freezing is a method of food preservation where food is kept at very low temperatures (usually below -18°C). At such low temperatures, enzyme activity and microbial growth are stopped, preventing spoilage.

Step 2: Analyze the given options.
- Freezing → Stops chemical and microbial reactions. Correct. - Drying → Removes moisture, does not involve very low temperature. - Fermentation → Controlled microbial activity, not inhibition of reactions. - Pickling → Uses salt, vinegar, or oil for preservation, not temperature.

Step 3: Conclusion.
Thus, the process described is freezing.
