### Topic: Changes in Percent Body Fat with Age

**Concept:**
With aging, body fat increases and muscle mass declines. The graph to the right shows the percent body fat in a group of adult women and men as they age from 25 to 75 years. Age is represented along the x-axis, and percent body fat is represented along the y-axis.

**Graph Interpretation:**
- **Axes:**
  - **X-axis (Horizontal):** Age (years), ranging from 25 to 75.
  - **Y-axis (Vertical):** Percent Body Fat, ranging from 0 to 40 percent.
  
- **Graph Details:**
  - The graph shows two lines indicating percent body fat for men and women:
    - **Women:** Generally shows an increasing trend in body fat percentage with age.
    - **Men:** The graph for men also demonstrates changes in body fat percentage, but it varies differently compared to women.
    
**Question:**
On what interval is the graph for women increasing?
  - A. (25, 65)
  - B. (65, 75)
  - C. (25, 75)
  - D. (20, 28)

From the provided options, the interval where the graph shows consistent increase should be identified.

**Answering the Question:**
To determine the interval on which the graph for women is increasing:
- **Examine the women's line on the graph:** It shows an increasing trend from ages 25 to 65.
- After 65, the trend plateaus or decreases slightly.

### Conclusion:
The correct option indicating the interval where the graph for women is increasing is **A. (25, 65)**.
