Detailed Solution & Explanation

A cumulative frequency distribution shows the accumulated frequencies up to a certain point. The graphical representation of this distribution is obtained by plotting cumulative frequencies on the vertical y-axis against the corresponding class boundaries on the horizontal x-axis. The resulting curve is known as an **Ogive** (or cumulative frequency curve). There are two main methods: 1. **Less than Ogive**: In this method, the upper boundaries of the class intervals are taken on the x-axis, and the corresponding 'less than' cumulative frequencies are plotted on the y-axis. 2. **More than Ogive**: In this method, the lower boundaries of the class intervals are taken on the x-axis, and the corresponding 'more than' cumulative frequencies are plotted on the y-axis. Since the question describes plotting cumulative frequency against class boundary, the resulting graph is an Ogive. Hence, **Option B** is the correct answer.
