The upper real limit for a class interval is obtained by adding half of the interval width to the upper class boundary. 
Here, the class interval is 20-25, so the interval width is 25-20 = 5. 
The upper class boundary is 25. 
Therefore, the upper real limit = 25 + (5/2) = 25.5. 
Hence, the best choice is B.
