1) In day 30 the max range is about 14, but take into account that this is the 75% quantile, therefore, the range should have a greater number. So It should be more than 14 and the only answer that checks it is A. You can check the same logic for the lower range of day 120. Therefore, Option A (15 to 8)
2) Just by observing we can see that the higher interquantile difference is in day 90. Option D
3) As the number of days increase, the light output tend to decrease, therefore they have an indirect relationship. Option B
