Quartiles divide a dataset into four equal parts. In this dataset, there are only 11 values, so we need to sort them first:

_eaaa24_e0
85
_c96c_
86
f9
_8172dfb62db9_TB4677_00

The median (second quartile) is in between the 5th and 6th values, which are both 6. The first quartile is in between the 3rd and 4th values, which are 3 and 6, respectively. The third quartile is in between the 8th and 9th values, which are both 9. Therefore, the first, second, and third quartiles are 3, 6, and 9, respectively. The answer is C.
