As the seeds mature, its water content decreases and reaches to ______ percent moisture by mass.

Options

A. `10-15`
B. `15-25`
C. `25-30`
D. `1-5`

Answer

To answer the question about the moisture content of seeds as they mature, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Seed Maturation**: As seeds mature, their water content decreases significantly. This is a crucial process for ensuring the seeds remain viable.

2. **Importance of Moisture Content**: The moisture content in seeds is vital for their viability. High moisture levels can promote the growth of molds and fungi, which can damage the seeds.

3. **Determining Optimal Moisture Levels**: While it is important to reduce moisture to prevent mold growth, it is also necessary to maintain a minimal level of moisture to ensure the seeds do not dry out completely.

4. **Analyzing Options**: The options given for the moisture content are:
- Option 1: 10-15%
- Option 2: 15-25%
- Option 3: 25-30%
- Option 4: 1-5%

5. **Evaluating the Options**:
- **Option 1 (10-15%)**: This range is considered minimal and suitable for maintaining seed viability without promoting mold growth.
- **Option 2 (15-25%)**: This is too high and could lead to mold development.
- **Option 3 (25-30%)**: This is also too high for seed viability.
- **Option 4 (1-5%)**: This is too low and would dry out the seeds.

6. **Conclusion**: Based on the analysis, the optimal moisture content for mature seeds is between 10-15% by mass.

### Final Answer:
The seeds mature and reach a moisture content of **10-15%** by mass.
