Options

A. Reduced light and hight humidity
B. Increased light and hight humidity
C. Reduced light and low humidity
D. Increased light and low humidity

Answer

### Step-by-Step Solution:

1. **Understanding Hardening**:
- Hardening is a process in which plants that have been grown in a controlled environment (like a greenhouse) are gradually acclimatized to the external environment. This helps them adapt to the natural conditions they will face outside.

2. **Purpose of Hardening**:
- The main goal of hardening is to prepare the plants for outdoor conditions, which may include changes in light, temperature, and humidity. This process encourages the plants to transition from softer growth conditions to firmer and harder growth conditions.

3. **Environmental Conditions During Hardening**:
- During the hardening process, plants are typically placed in conditions that differ from their original growing environment. This includes changes in light intensity and humidity levels.

4. **Analyzing the Options**:
- **Option 1**: Reduced light and high humidity.
- **Option 2**: Increased light and high humidity.
- **Option 3**: Reduced light and low humidity.
- **Option 4**: Increased light and low humidity.

5. **Correct Answer**:
- The correct condition for hardening is **reduced light and high humidity**. This combination helps the plants gradually adjust to the harsher conditions they will face outside.

### Final Answer:
During hardening, plants are kept under **reduced light and high humidity**.
