Hey Paul, let me see if I can help here. The stimulus is saying that correlation between two thing does not prove one of them causes the other, because something else could be causing both things. Be careful about how you paraphrase the stimulus - the author never said that this outside cause issues is more often the case, only that it is often the case. That doesn't have to mean most of the time, because "often" is very subjective. Maybe 30% of the time is enough to say it is often the case? Bringing in "most often" to your analysis could cause you real trouble when you get to the answers!
Also, the argument is not saying that two things are the same thing - it's saying that they are often caused by the same outside cause, a third thing. "Such association is often due to conditions of both types being effects of the same kind of cause" means that the two things that correlate with each other are not a cause and an effect, but are both the effects of something else. The author is saying that something is causing the two correlated things to occur, but they are not necessarily causing each other to occur. I might be sad every time my wife is sad, but that doesn't mean that her sadness causes mine or that mine causes hers. Often there are just things that make us both sad at the same time.
Answer A is incorrect because it does not draw a conclusion about a third, outside cause. Instead, it denies that there is any causal relationship and claims instead that two thing thought to be correlated are really just two different names for the same thing.
Answer B is correct because, like my example above, it shows two things that are correlated and suggests that rather than one of them causing the other, some third thing could be causing both. That matches the stimulus! Not that two things ARE the same, but they could both be CAUSED BY the same thing.
