As when the forest has been cleared there is nothing to reduce the amount of rain from hitting the soil, the rain washes away all the nutrients and sometimes even soil.
Hope this helps

The Correct Answer is A

Explanation:

The great temperature and precipitation of tropical rainforests generate lifeless nonchemical elements in the soil to disintegrate more swiftly than in other environments, thus liberating and wasting its nutrients immediately. A large amount of rain in tropical rainforests removes nutrients out of the soil more immediately than in other environments.
