Correct Answer: Option (B)
Explanation:

 To find the median of a set of numbers, you first need to order the numbers in ascending or descending order.

{32, 33, 48, 68, 70, 80, 86}

The median is the middle value when a data set has an odd number of observations.

The middle value of 7 numbers is the 4th one, which is 68.

So, the median of this set is 68.
