Solution

The correct option is A 1
Here, the horizontal axis represents the month and the vertical axis represents the frequency of students having birthdays in a particular month.

The scale of the vertical axis has an interval of 2 units.

Hence, the distance between two horizontal lines is two units.

From the graph, it is observed that the bar corresponding to August is the smallest.

$\Rightarrow$ It lies midway between 0 and 2 units.

Hence, the bar has a height of 1 unit.

$∴$ Only one student has his/her birthday in August.
