**Explanation:**
To find the class mark of a class interval, we need to find the average of the lower class limit and the upper class limit.
In this case, the class interval is 15.5 - 20.5.
- The lower class limit is 15.5.
- The upper class limit is 20.5.
**Calculating the class mark:**
To find the class mark, we add the lower class limit and the upper class limit and divide the sum by 2.
Class mark = (Lower class limit + Upper class limit) / 2
Class mark = (15.5 + 20.5) / 2
Class mark = 36 / 2
Class mark = 18
Therefore, the class mark of the class interval 15.5 - 20.5 is 18.
**Explanation of options:**
a) 15.5: This is the lower class limit, not the class mark.
b) 20.5: This is the upper class limit, not the class mark.
c) 18: This is the correct answer. It is calculated by finding the average of the lower class limit and the upper class limit.
d) 5: This is not relevant to the given class interval.
Therefore, the correct answer is option 'C' which represents the class mark of the class interval 15.5 - 20.5.
To find the class mark of a class interval, we need to find the average of the lower class limit and the upper class limit.
In this case, the class interval is 15.5 - 20.5.
- The lower class limit is 15.5.
- The upper class limit is 20.5.
**Calculating the class mark:**

Class mark = (Lower class limit + Upper class limit) / 2
Class mark = (15.5 + 20.5) / 2
Class mark = 36 / 2
Class mark = 18
Therefore, the class mark of the class interval 15.5 - 20.5 is 18.
**Explanation of options:**
a) 15.5: This is the lower class limit, not the class mark.
