The median is the middle value of a data set when the values are arranged in order. Since there are seven students in total, the median would be the fourth value.
Arranging the values in order, we have: 6, 6, 7, 7, 8, 9, 9.
The fourth value is 7, so the median of the data set is 7.
Therefore, the correct answer is A. 7.
