The most appropriate reason for storing green-colored apples at low temperature is

Options

A. The rate of photosynthesis is reduced.
B. Respiration and photosynthesis are completelt inhibited.
C. The rate of respiration is reduced.
D. The rate of photosynthesis and respiration are reduced.

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the most appropriate reason for storing green-colored apples at low temperatures.

2. **Identifying the Options**: The options provided are:
- A) Rate of photosynthesis is reduced
- B) Respiration and photosynthesis are completely inhibited
- C) The rate of respiration is reduced
- D) The rate of photosynthesis and respiration are reduced

3. **Analyzing the Effects of Low Temperature**: When green apples are stored at low temperatures, several physiological processes occur:
- The cellular activities, including respiration, slow down.
- This reduction in activity helps to conserve energy.

4. **Focusing on Respiration**: Among the processes affected, respiration is particularly important because:
- Lower temperatures lead to a decrease in the rate of respiration.
- A reduced respiration rate means that the apples will use less energy and age more slowly.

5. **Conclusion**: The most appropriate reason for storing green-colored apples at low temperature is that the rate of respiration is reduced. This reduction helps in prolonging the shelf life of the apples by slowing down their aging process.

### Final Answer:
The most appropriate reason for storing green-colored apples at low temperature is **the rate of respiration is reduced**.
