Answer:
C) believing that association is the same as causation
Explanation:
Two completely independent events can be associated because just by chance they occurred during the same period of time, e.g. I found a $5 bill on the park and I bought lottery ticket and I won a prize. That doesn't mean that every time I will find money on the ground I will win a lottery prize.
Causation on the other hand refers to a strict cause and effect relationship, e.g. I don't like to wash my hands before eating and I have the tendency of getting sick. The fact that I don't wash my hands is directly related to getting sick.
