The moist, warm forests that are usually located near the equator are called rain forests. Therefore, the correct answer is option C.
Temperate forests (Option A) are forests that experience four distinct seasons and are located in regions with moderate climates, while coniferous forests (Option B) are forests dominated by cone-bearing trees such as pines, spruces, and firs. Boreal forests (Option D), also known as taiga, are forests that are dominated by cold-tolerant evergreen trees and are found in high-latitude regions.
