Solution

The correct options are
A
The highest strength of the class was in the year 2014

C
The average number of students in the year 2012 and 2014 was equal to the number of students in the year 2010

Height of the bars in the graph represents the number of students.

From the bar graph, the tallest bar occurs in the year 2014. So, in the year 2014, the strength of the class was the highest.

The average number of students in the year 2012 and 2014 = $\frac{80 + 90}{2} = 85$ .
From the graph, in the year 2010, the strength of the class was 85. So, this statement is true.

In the year 2012 and 2015, the height of the bars is the same. So, in those years the number of students was the same equal to 80.

The lowest height of the bar occurs in the year 2013. So, the lowest strength of class is in year 2013 and equal to 50.
