Gorge and Hattie want to perform a set of experiments to test the optimal water and sunlight levels of a certain species of pea plant.Gorge decides to test the amount of water that the species needs to thrive. He takes 24 pea plants and separates them into four equal groups and gives each group a different daily amount of water. He keeps all other environmental conditions the same for each group. He measures the initial height of all the pea plants and then measures their growth after one month.Gorge averages the data from the individual pea plants and comes up with an average for each group, which he reports in the table below.After Gorge's experiment is complete, Hattie decides to test the optimal sunlight exposure for this species. She takes 24 pea plants and separates them into four equal groups and exposes each group to a differing daily amount of sunlight. She keeps all other environmental conditions the same for each group, including giving each group 15 mL of water daily. She measures the initial height of all the pea plants and then measures their growth after one month.Hattie averages the data from the individual pea plants and comes up with an average for each group, which she reports in the table below.Which of the following conclusions can be made based on the results of these investigations? A. This species of pea plant grows best when given 15 mL of water and four hours of sunlight daily. B. This species of pea plant grows best when given 15 mL of water and three hours of sunlight daily. C. This species of pea plant grows best when given 5 mL of water and one hour of sunlight daily. D. This species of pea plant grows best when given 5 mL of water and four hours of sunlight daily.
