Solution

The correct options are
A by using histogram
C without using histogram
D without using cumulative frequency
Construction of frequency polygon for a grouped frequency distribution can be done with or without using the histogram.

We need class intervals for the calculation of class marks and frequency points. Plot class marks and frequency points on the graph and join the successive points to get the frequency polygon.

There is no need for calculating the cumulative frequency draw histogram.
