The correct option is this: SHE SHOULD TRY THE EXPERIMENT WITH A POTTED PLANT WITH ROOTS AND OBSERVE ANY COLOR CHANGE.
After the formulation of hypothesis, the next thing to do is to carry out an experiment which is designed to test out the observation that was made. The next thing for Maria to do is to carry out an experiment to confirm her hypothesis.

Maria should try the experiment with a potted plant with roots and observe any color changes. This will help her conclude better about her presumed hypothesis- that the color reaches the flower through the stem.
A potted plant is living and to carry out experiment on a living plant is the best possible way to confirm Maria's hypothesis.
