Median of 73 scores must be the 37th score when all the scores are arranged in increasing or decreasing order. In the score interval 50-79 there are (2 + 10 + 16) = 28 scores. Hence the 37-th score is not in this interval.

But in the score interval 50-89 there are (2 + 10 + 16 + 27) = 55 scores. Hence the 37-th score is in the score interval 80-89.

The correct answer is C.
