The correct option is C forests
In some areas, we get plenty of sunlight and a high amount of rainfall. A large number of trees grow in such areas. They are called forests.
Then, there are areas where the rainfall is low. In such areas, vast stretches of tall grass are present, with a few trees growing here and there. They are called grasslands.
There are also areas where the rainfall is very low. In such dry regions, only small thorny plants grow. This kind of vegetation are called shrubs.
