C.

D.

Answer 1

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that the data set, we first write it in continuous interval.

Ages               Number of listeners

0.5-10.5                         0

10.5-20.5                       3

20.5-30.5                      19

30.5-40.5                      42

40.5-50.5                      33

50.5-60.5                       8

60.5-70.5                        1

As we know that

Histogram is used to plot the frequency given in continuous data that is divided into classes.

Hence, Histogram is the best to illustrate this data.

Therefore, Option 'D' is correct.
