Which of these would be the best way......? (Please click for details)?

Which of these will be the best way to find whether adding fertilizer makes tomato plants produce more potatoes? A. Increase the amount of water given to five identical tomato plants B. Give different amounts of fertilizer to five identical tomato plants C. Measure the height of five different tomato plants D. Count the number of tomatoes on five different tomato plants I think it is B, but I wanted to ask you guys to make sure. Thank you! Oops, I was thinking about potatoes. >.< I meant tomatoes. Thanks for the correction!
