In order to find the midpoint of a class interval, we need to take the average of the upper and lower class limits. 
The class with the greatest frequency is 1500-1599, whose lower limit is 1500 and upper limit is 1599. 
Therefore, the midpoint for this class is (1500+1599)/2 = 1550. 
Thus, the answer is B) 1500.
