The equatorial rainforest is a type of forest that is found near the Earth`s equator. It is known for its high levels of rainfall and biodiversity. The correct answer to the question is option 3, "Selva."

Option 1, "Savanna," is incorrect. Savannas are characterized by grasslands with scattered trees and are found in tropical and subtropical regions, but they are not the same as equatorial rainforests.

Option 2, "Campos," is also incorrect. Campos refer to open grasslands that are found in South America, particularly in Brazil, but they are not the same as equatorial rainforests.

Option 4, "Lanose," is not a term associated with equatorial rainforests.

Therefore, the correct answer to the question is option 3, "Selva," which is another term used to refer to the equatorial rainforest.
