Correct Answer:

Option A. Independent Variable

Solution: An independent variable is the one which can have any value in its Domain and its value does not depend on any other factor. Rate of Cancer, for example, is not an independent variable in this case as it is depending on the age of the person under consideration. So rate of cancer is a dependent variable. The difference between independent and dependent variable must be clear to perform any sort of analysis.
