Where would a natural grassland most likely be found? 

A)  where annual precipitation exceeds 115 cm 
B)  in the zone lying between a forest and a desert 
C)  in places that are suitable for forests 
D)  where drought and fire are very rare

Grasslands are typically found in areas where there is not enough rainfall to support a forest but too much rainfall to support a desert. This makes the area between a forest and a desert (known as a biome transition zone) a prime location for grasslands. Option A can be ruled out as it mentions an annual precipitation of over 115 cm, which is not typical for grasslands. Option C is incorrect as grasslands are not suitable for forests due to the lack of trees and shade. Option D is also incorrect as drought and fire are actually common occurrences in grasslands.
