You haven't given all the data examples as there is just one box plot.
If there are only two choices of Data then go with the first one on picture as it handles data up to 24
The first data on picture also balances the data 15, 17 and 19 and 19 as the first two quarters. So seems to draw the median at 19 and out of the two examples is more consistent to quarters 1-4 = 15-24
Step-by-step explanation:
I would look for answers that represent the whole data
1st qtr = 13-15 = 2
2nd qtr = 15-19 = 4
3rd qtr = 19- 21 = 2
4th quarter = 21-24 = 2
As 2nd qtr is twice as big it still only represents 25% data
