When Jeremy returned home after vacation, he noticed that his new plant had not grown. His mother, a florist, told him that it was because the plant was not getting enough sunlight. He moved his plant closer to the window to get more sunlight. How can Jeremy best support the idea that his plant needs more sunlight? Ask his mother to make the plant better. Wait and see what happens to the plant. Remove the plant from direct sunlight after a week. Ask his science teacher at school what she thinks could be the reason.

Wait and see what happens to the plant.

Explanation:

The best course of action for Jeremy would be to wait and see what happens to the plant after moving it closer to the window to get more sunglight.

If the plant grows after observing it for some times, he can conclude that light has been a major hindrance to the growth and more sunlight would benefit the plant. If the observation is otherwise, then Jeremy can conclude that the lack of growth observed is not due to light.

it's filtration, but this is an assumption so my apologies if i got this
