A. For a lot of people, drinking beer causes a desire for ice cream, or vice versa.

Explanation:

We can conclude from the monthly sales that when a lot of people drink beer, a lot of people tends to take ice cream, and when less people take beer, less people tends to take ice cream, the fact shows that there is a correlation between the sales of beer and the sales of ice cream.
