A.

Step-by-step explanation:

To find mean, average the numbers in the data set by adding them together and dividing by the number of values.

(96 + 77 + 82 + 91 + 89) / 5 = 87.

To find median, take the "middle" value of the data set. To find this, you can sort the numbers in ascending order and remove the same amount of values from each side.

77 / 82 / 89 / 91 / 96, the median is 89.

Therefore, the mean is less than the median.
