The independent variable is the variable that is deliberately changed or manipulated in an experiment. In this case, the dosage given to participants is intentionally varied, making it the independent variable.

The correlation coefficient is a statistical measure used to determine the strength and direction of a relationship between two variables, and is not relevant in this context. "Invariable" is not a valid option as it is a term used to describe something that does not vary or change, which does not apply to the dosage variations in the medication testing experiment.
