none, not even logic can let you predict if someone who enjoys exercising will earn more or not.

If you go from an extremely barbaric statistical average of a few hundred thousand people, however, you might get either A or D (in the order you cited), seeing as exercising is good for both brain and body, and laziness tends to go against success 

(but there is a philosophical school that says science and progress is basicly due to man's inherent laziness... )

Personally, I'd seriously ask whoever made the question to put the goals a little closer together, as:

 Money earned in life<-> Willingness to exercise in past

Is a rather weak causal link, and we're talking about a gap of several years...




But yeah, A or D, depending on the statistical population studied... unless you have an:
 E) No causality is certain.

Hope my extreme purism when it comes to acceptable science helped XD.

Thanks :).
I've always taught it's essential to present both a for and against in one's argumentation, otherwise, it's too easy to turn a blind eye to everything that's against the opinion one's trying to protect.
