(D) First,calculate the cumulative frequency $(cf)$ for each class:$1$. Class $10-25$: $cf = 5$$2$. Class $25-40$: $cf = 5 + 21 = 26$$3$. Class $40-55$: $cf = 26 + 21 = 47$$4$. Class $55-70$: $cf = 47 + 8 = 55$$5$. Class $70-85$: $cf = 55 + 25 = 80$$6$. Class $85-100$: $cf = 80 + 20 = 100$The total frequency $n = 100$.Calculate $\frac{n}{2} = \frac{100}{2} = 50$.The median class is the class whose cumulative frequency is just greater than or equal to $\frac{n}{2} = 50$.Looking at the cumulative frequencies: $5, 26, 47, 55, 80, 100$. The first cumulative frequency greater than $50$ is $55$,which corresponds to the class $55-70$.Therefore,the median class is $55-70$.

Area of land (in hectares)	$1-3$	$3-5$	$5-7$	$7-9$	$9-11$	$11-13$
Number of families	$20$	$45$	$80$	$55$	$40$	$12$

Class	$0-10$	$10-20$	$20-30$	$30-40$	$40-50$	$50-60$	$60-70$	$70-80$
Frequency	$2$	$4$	$10$	$20$	$18$	$20$	$16$	$10$

The median class in the following frequency distribution is $\ldots \ldots \ldots \ldots .$
