The correct answer is option b. "plants in the rainforest release a large amount of water to the atmosphere".
Explanation:
It is considered that rainforests are partly self-watering because plants itself promote precipitation by releasing a large amount of water to the atmosphere. This process known as transpiration helps to create a thick cloud, which helps to create an atmosphere humid and warm. Plants' transpiration is one reason why rainforests have more precipitation than deserts.
