(B) composite number is a positive integer greater than $1$ that has at least one divisor other than $1$ and itself.The first five composite numbers are $4, 6, 8, 9, 10$.To find the median,we arrange the data in ascending order (which is already done: $4, 6, 8, 9, 10$).Since the number of observations $(n = 5)$ is odd,the median is the middle term,which is the $\left(\frac{n+1}{2}\right)^{th}$ term.Median $= \left(\frac{5+1}{2}\right)^{th} = 3^{rd}$ term.The $3^{rd}$ term in the sequence is $8$.Therefore,the median is $8$.
