Apple required a low temperatrue for flowering and fruiting

Options

A. `10^(@)C`
B. `7^(@)C`
C. Below `7^(@)C`
D. `10^(@)-15^(@)C`.

Answer

**Step-by-Step Solution:**

1. **Understanding the Requirement**: The question states that apples require low temperatures for flowering and fruiting. This indicates that there is a specific temperature range that is optimal for these processes.

2. **Analyzing the Options**: The given options are:
- 10 degrees Celsius
- 7 degrees Celsius
- Below 7 degrees Celsius
- 10 to 15 degrees Celsius

3. **Temperature Tolerance**: It is known that apple trees (Malus domestica) require a period of cold temperatures, often referred to as "chilling hours," to break dormancy and initiate flowering.

4. **Identifying the Critical Temperature**: From the information provided, it is indicated that flowering begins at around 7 degrees Celsius or lower. This suggests that apples thrive in conditions that are colder than this threshold.

5. **Conclusion**: Based on the analysis, the best answer is "below 7 degrees Celsius," as this temperature is necessary for the flowering and fruiting of apple trees.

6. **Final Answer**: Therefore, the correct option is **below 7 degrees Celsius**.
