Nicole plans an investigation to determine the Sun's role in the water cycle. She places a tomato plant in the sunshine and one in a darkened room. She puts a clear plastic bag around a leaf on both plants. She waters the plants daily with the same amount of water. After two days, she notices that there are water droplets on the inside of the plastic bag on the plant that is in the sunshine. What part of the water cycle does her experiment show?

• It shows how sunlight triggers infiltration in the plant.

• It shows how sunlight triggers evaporation in the plant.

• It shows how sunlight triggers precipitation in the plant.

• It shows how sunlight triggers transpiration in the plant.
