Explanation:

Step1: Recall box - plot components

In a box - and - whisker plot, the box represents the interquartile range (IQR). The line inside the box (the median of the data set) represents the second quartile ($Q_2$), which is also the median of the entire data set.

Step2: Identify the median line

Looking at the box - and - whisker plot, the vertical line inside the box (the median line) is at the value of 50 (by observing the scale on the x - axis, where the marks are at 40, 45, 50, 55, 60 and the median line of the box aligns with 50).

50
