To create a box plot for the provided dataset (15, 20, 20, 25, 26, 28, 28, 30, 32), we need to calculate the five-number summary: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum.

1. **Minimum**: 15
2. **Maximum**: 32
3. **Median (Q2)**: The middle value is 26 (the average of the 4th and 5th values, which are 25 and 26).
4. **First Quartile (Q1)**: The median of the first half (15, 20, 20, 25) is 20.
5. **Third Quartile (Q3)**: The median of the second half (26, 28, 28, 30, 32) is 28.

With these values, we summarize:
- Minimum: 15
- Q1: 20
- Median (Q2): 26
- Q3: 28
- Maximum: 32

The box plot would feature:
- A box from Q1 (20) to Q3 (28) with a line at the median (26).
- Whiskers extending from the minimum (15) to the left and maximum (32) to the right.

When reviewing potential box plots, look for one that:
- Displays the box correctly from 20 to 28.
- Has a line at 26 indicating the median.
- Extends to 15 on the left and 32 on the right.

Since I cannot see the box plots you are referring to, you will need to check the options against the points mentioned above. The correct box plot will have the dimensions listed.
