Answer
A
87 percent
B
79 percent
C
82 percent
D
92 percent

Explanation

Put the scores in order from least to greatest: 72, 74, 76, 78, 80, 82, 92, 92. Since there are 8 scores, the median is the average of the two middle scores, 78 and 80. Their average is (78 + 80) ÷ 2 = 79 percent, so the median is 79 percent.
