I think the correct answer from the choices listed above is option C. The purpose of a controlled experiment is to  examine whether one variable causes a change in another. An independent variable is the only factor that is allowed to be adjusted, with the dependent variable as the factor that the independent variable will affect.

Answer: C. to examine whether one variable causes a change in another.

Explanation:

A controlled experiment is the one where a control variable is used which is used as a benchmark or standard for comparing the changes occurring in a dependent variable due to the changes occurring in an independent variable by undergoing manipulation and alteration.

On the basis of the above explanation, C. to examine whether one variable causes a change in another is the correct option.
