Correct Answer - Option 4 : (A)

Concept used:

In statistics, a frequency distribution is a list, table or graph that displays the frequency of various outcomes in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval

Calculation:

The number of people with age group less than 20 = 2 i.e (15, 19)

The number of people with age group between 20 and 40 = 4 i.e (34, 24, 35, 23)

The number of people with age group between 40 and 60 = 5 i.e (45, 45, 56, 55, 52)

The number of people with age group between 60 and 80 = 7 i.e (69, 74, 67, 77, 65, 67, 78)

The number of people with age group between 80 and 100 = 2 i.e (89, 91)

∴ The correct answer is
