Final answer:
Tropical rainforests receive between 80-400 inches of rain per year, with annual ranges specifically from 250 cm to over 450 cm.
Step-by-step explanation:
The average amount of precipitation a tropical rainforest receives is between 80-400 inches of rain per year, which aligns with option c. More precisely, the annual rainfall in tropical rainforests ranges from roughly 250 cm to over 450 cm (approximately 98.4 to 177.2 inches) with significant seasonal variation. Even in drier months, the rainfall in these biomes can exceed the annual rainfall of others, like deserts.
