Correct Answer Explanation
The class 0–10 had the lowest frequency of 1 — only one student scored between 0 and 10.
Key Points:
- The lowest frequency class (0–10) shows that very few students failed badly.

- Frequency expressed as a proportion of total frequency is called relative frequency.
- Relative frequency of 0–10 = 1/100 = 1%
