Detailed Solution

We have to check that for drawing a frequency polygon of a continuous frequency distribution, we plot the points whose ordinates are the frequencies of the respective classes and abscissa are respectively the class marks of the classes.
We know that the abscissa of the points is the midpoint of the classes of a frequency distribution.
The x-axis represents the frequencies of the frequency distribution, and the y-axis represents the abscissa.
The abscissa represents the midpoint of the classes; therefore, the abscissa is the class marks.
Thus, the given statement is true.
Therefore, option 1 is correct.
