Definition: A histogram visualises the distribution of data over a continuous interval or certain time period. Each bar in a histogram represents the tabulated frequency at each interval.

According to the given histogram,

0-20 years occur 15 times,

21-40 years occur 40 times,

41-60 years occur 40 times,

61-80 years occur 15 times.

This shows that the data is symmetrical and the majority of the attendees were between the ages of 21 and 60 (40 times).

What is an histogram?

An histogram is a graph that shows the number of times each element of x was observed.

In this problem, the histogram means that:

15 people were between 0 and 20 years.

40 people were between 21 and 40 years.

40 people were between 41 and 60 years.

15 people were between 61 and 80 years.

Considering the reference of 40 years old, the histogram is symmetric, and due to it's higher height, the majority of the people are between 21 and 60 years, hence option B is correct.
