Tobias notices that a particular kind of flower comes in many slightly different shades of pink. In other places, the same flower may be many shades of purple or even blue. He knows that some flowers' colors depend on where they are planted, while others' are determined by their breed. He hypothesizes that the different colors of these flowers are genetically different. Which of the following experimental setups is best for testing this hypothesis?
A. Tobias experiments with using different fertilizers and composts, such as pine needles, observing if the presence of these substances will change the colors of the surrounding flowers.
B. Tobias transplants several of the flowers, swapping some from the middle of a pink patch with some in the middle of a blue patch. He observes the results.
C. Tobias collects data on many patches of the flowers he comes across. He records flower color, how much shade the plant gets, observes how moist the ground is, and measures the ground's pH. He compares his data and looks for patterns.
D. Tobias takes home several pink flowers, several purple flowers, and several blue flowers in pots. He breeds and interbreeds them, observing the results.
