To find the third quartile, we first need to arrange the data set in order from smallest to largest: 
7, 7, 9, 10, 12, 14, 16, 41 
Then, we divide the data set into two halves. The median of the lower half (also known as the second quartile or Q2) is 10, and the median of the upper half is 16. Therefore, the third quartile (also known as Q3) is the median of the upper half, which is 15.5. Therefore, the answer is B.
