(C) To find the median,we first calculate the cumulative frequency $(cf)$:ClassFrequency $(f)$Cumulative Frequency $(cf)$$0-10$$2$$2$$10-20$$6$$8$$20-30$$8$$16$$30-40$$16$$32$$40-50$$20$$52$$50-60$$18$$70$$60-70$$16$$86$$70-80$$14$$100$Total frequency $N = 100$. So,$N/2 = 50$.The cumulative frequency just greater than $50$ is $52$,which corresponds to the class interval $40-50$.Thus,the median class is $40-50$.Here,$l = 40$,$f = 20$,$cf = 32$,and $h = 10$.Using the median formula: $	ext{Median} = l + \left( \frac{N/2 - cf}{f} ight) 	imes h$$	ext{Median} = 40 + \left( \frac{50 - 32}{20} ight) 	imes 10$$	ext{Median} = 40 + \left( \frac{18}{20} ight) 	imes 10 = 40 + 9 = 49$.
