We need to group the data in classes of 1400 up to 1600, 1600 up to 1800, 1800 up to 2000, and so on.

- There are 9 students who scored between 1400 and 1600.
- There are 15 students who scored between 1600 and 1800.
- There are 6 students who scored between 1800 and 2000.

Therefore, the answer is the number of students who scored between 1800 and 2000, which is 6. So the answer is choice C.
