Answer
Brief Explanations:
In an experiment to study the effect of water - amount on plant growth, the amount of water is the independent variable that is being changed. Constants or controls are factors that are kept the same to ensure that only the independent variable (water amount) affects the dependent variable (plant growth). The type of plant, amount of soil, and amount of time in the sun should be kept constant.
Answer:
C. the amount of water
