Which pair of events is likely to be positively correlated?

A) stock prices of computer companies and of tire companies
B) hurricane damage in Florida and earthquake damage in California
C) sales of ice cream and cars on a hot summer day
D) a week-long power outage due to a large hurricane and battery sales

A positive correlation means that as one event increases, the other is likely to increase as well. In the case of a week-long power outage due to a large hurricane, the demand for batteries is likely to increase as people seek alternative power sources, indicating a positive correlation between these two events.
