Fruit, meat and milk are preserved at room temperature through the process of
(a) Pasteurisation
(b) Fridge
(c) Dehydration
(d) Vernalisation

Options

A. Pasteurisation
B. Fridge
C. Dehydration
D. Vernalisation.

Answer

To solve the question regarding how fruit, meat, and milk are preserved at room temperature, let's analyze the options step by step:

### Step 1: Understanding the Preservation Methods
We need to identify which method allows for the preservation of fruit, meat, and milk at room temperature.

### Step 2: Evaluating Each Option
1. **Pasteurization**: This method involves heating food to kill harmful microorganisms. However, it requires high temperatures, which contradicts the requirement of preservation at room temperature. Therefore, this option is incorrect.

2. **Fridge**: Refrigeration involves storing food at low temperatures to slow down microbial growth. Since this method operates at lower temperatures than room temperature, it is not suitable for this question. Thus, this option is also incorrect.

3. **Dehydration**: This process, also known as drying, removes moisture from food, which prevents microbial growth. Dehydration can occur at room temperature, making it a viable method for preserving food items like fruit, meat, and milk. Therefore, this option is correct.

4. **Vernalization**: This is a biological process that induces flowering in plants and is unrelated to food preservation. Hence, this option is incorrect.

### Conclusion
The correct answer is **(c) Dehydration**, as it allows for the preservation of fruit, meat, and milk at room temperature by removing moisture and preventing microbial growth.
