Options

B. 50 months
C. 100 years
D. 25 years

Answer

To determine the age of the tree based on the number of annual rings observed in its cross-section, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Annual Rings**: Annual rings are layers of growth that trees produce each year. Each ring represents one year of growth.

2. **Identifying the Number of Rings**: In this case, the cross-section of the tree trunk shows 50 annual rings.

3. **Calculating the Age**: Since each annual ring corresponds to one year of growth, we can conclude that the number of rings directly indicates the age of the tree.

4. **Final Calculation**: Therefore, if there are 50 annual rings, the age of the tree is 50 years.

### Conclusion:
The age of the tree is **50 years**.
