Right off the bat, I think I would say D, but I think the question wants to know how you would date a rock BEFORE we were able to do that. Maybe C, different rocks form and age at different rates and under different circumstances...

I say B. If you are able to identify the fossils in a rock, you would be able to tell when the lived - therefore you would know how old the rock layer is.
