Explanation:

An independent variable is the factor that is changed or manipulated in an experiment. In the experiment "Does sugar water affect the growth of plants?", the presence of sugar in the water is what is being changed (some plants get sugar - water, some get regular water). The amount of sunlight and water should be kept constant (controlled variables) to ensure a fair test. The growth of plants is the dependent variable (what is measured as a result of the change in the independent variable).

Answer:

A. presence of sugar in the water
