which set of variables has correlation and causation?\na. distance traveled and money spent on gas\nb…

Brief Explanations:

Causation means one variable directly affects another. Correlation is a relationship between variables. For distance traveled and money spent on gas, more distance usually requires more gas, so there is both a relationship (correlation) and a cause - effect (causation) as gas is consumed for travel. For the other options, distance traveled doesn't directly cause money spent on snacks, number of drinks consumed, or time spent listening to music.

Answer:

A. distance traveled and money spent on gas
