________ is the quartile representing the 50^th percentile.

A) Q₁
B) Q₂
C) Q₃
D) Q₄

In the quartile notation, the first digit represents the quartile number and the second and third digits represent the percentiles. As the given percentile is 50.1, we know it lies between the 50th and 51st percentiles. The quartile that contains this range is the second quartile, represented by the digit 2. Therefore, the first digit of the quartile is 2. The second and third digits are obtained by subtracting the lower end of the range (50) from the given percentile (50.1), giving us 0.1. Multiplying this by 100 gives us 10. Therefore, the quartile is Q₂.
