Answer

Answer:

D. Tap water is one of the three test conditions of the independent variable, the type of water.

Brief Explanations:

In the experiment, the independent variable is the type of water (tap, distilled, carbonated). Tap water is just one of these test - condition options for the independent variable, not a control group or a controlled variable. And it's not the only condition to affect the dependent variable (plant growth).
