To find the third quartile, we need to arrange the data set in ascending order:

2, 3, 4, 5, 5, 6, 7, 8, 12, 14, 19, 35

There are 12 values in the data set, so to find the third quartile (Q3), we need to find the median of the upper half. The upper half consists of:

12, 14, 19, 35

The median of this set is (14 + 19)/2 = 16.5. Therefore, the third quartile is 16.5 or choice B.
