A study finds that as monthly ice cream sales rise, monthly drowning
deaths also rise, with a strong positive correlation. What is the most
reasonable conclusion?

Eating ice cream causes drowning, because the correlation is
strong.

Drowning incidents cause people to buy more ice cream.

The correlation is fake and should be ignored.

A lurking variable (warm weather) likely drives both, so the
correlation does not show that one causes the other.
