Which of the following is true about tropical rainforests?

Tropical rainforests are characterized by their high levels of rainfall, typically receiving between 60 to 100 inches (150 to 250 centimeters) of rain annually. This abundant precipitation is a critical factor in supporting the lush vegetation and diverse ecosystems found in these forests. The consistent warm temperatures and high humidity levels contribute to the rich biodiversity that tropical rainforests are known for, making them one of the most biologically diverse ecosystems on the planet.

In addition to the significant rainfall, tropical rainforests often feature dense canopies filled with a variety of tree species, wildlife, and plant life, which thrive in such a wet environment. This combination of factors is what makes option C the correct answer about tropical rainforests.
