Just taking the wording of the question and breaking it apart will lead you to the right answer. 

1) If rain is causing car washes, rain is related to the INDEPENDENT VARIABLE and "... the more often it rains ... ", the word often is indicating a frequency of rain. So, you have an Independent variable based upon the frequency of rain. Choice C would be the correct response.

2) If rain is the independent variable then, from the problem statement "... the more often I have to wash ...", that word often indicates a frequency of washes. Again this supports Choice C.
