Michael is performing an indoor experiment with plants to determine how they react to light. which of the following is a testable hypothesis that is relevant to his experiment? a. the final height of a plant is determined by the average outdoor temperature of an area. b. the angle at which indoor plants grow is related to the location of natural light sources such as windows. c. placing plants in clay pots can affect the number of times the plant needs to be watered each week. d. the overall health of a plant depends on whether or not it is properly fertilized.

The angle at which indoor plants grow is related to the location of natural light sources such as windows.

Option B.

Explanation:

During the process of the growing of the plants, one of the most important factors is the light of the sun and the warmth that the sun gives to the seeds and the growing plant for it's growth.

If the plants are growing indoor that is inside a building, then the angle at which the sun light will come and reach the plant is very important. So the plants have to be kept at a particular angle so that they get the proper amount of sunlight needed for their growth.
