(B) In the formula for the mode,$Z = l + \left( \frac{f_{1} - f_{0}}{2f_{1} - f_{0} - f_{2}} ight) 	imes c$,the terms are defined as follows:$l$ is the lower limit of the modal class.$f_{1}$ is the frequency of the modal class.$f_{0}$ is the frequency of the class preceding the modal class.$f_{2}$ is the frequency of the class succeeding the modal class.$c$ is the class size or class length.Therefore,$f_{0}$ represents the frequency of the class preceding the modal class.

Class	$0-10$	$10-20$	$20-30$	$30-40$	$40-50$
Frequency	$7$	$16$	$25$	$32$	$20$
