Detailed Solution & Explanation

In frequency distributions, class intervals can be written in two ways: 1. **Inclusive Series**: The upper limit of a class is not equal to the lower limit of the next class (e.g., 10−19,20−29,30−39\displaystyle 10-19, 20-29, 30-39). This introduces gaps between classes, making the series discontinuous. 2. **Exclusive Series**: The upper limit of a class is exactly equal to the lower limit of the succeeding class (e.g., 10−20,20−30,30−40\displaystyle 10-20, 20-30, 30-40). Here, the value equal to the upper limit is excluded from that class and included in the next class. Because the class boundaries are contiguous with no gaps, the **Exclusive series** is continuous. - Open-ended or close-ended series refer to whether the boundary limits of the first and last classes are specified, and they do not define continuity. - Unequal class intervals do not guarantee continuity unless they are structured in an exclusive format. Thus, the Exclusive series is continuous. Hence, **Option B** is the correct answer.
