Explanation:

In an experiment, the independent variable is the one that the scientist deliberately manipulates or changes to observe its effect on the dependent variable. The dependent variable is what is measured and affected by the independent variable. Controlled variables are kept constant to ensure that only the independent - variable's change affects the outcome. The term "experimental" is not a standard name for this type of variable in the context of experimental design.

C. independent
