months?
A) 1.5 inches
B) 2.0 inches
C) 2.5 inches

2.5 inches

Step-by-step explanation:

From the graph, it is evident that the steepest part of the graph is the last part, between the months of September and October. The value for September is 5 while that for October is 2.5. Getting the difference of the two, we obtain that 5-2.5=2.5

This is the highest change in monthly rainfall between two consecutive months
