The correct answer is A. Of a total number of people with pets, how many people have dogs vs. how many people have cats.
Explanation: A scatter plot graph is used to depict the relationship between two quantitative variables. Option A compares the number of people who have dogs versus the number of people who have cats, which can be plotted on a scatter plot since both variables are quantifiable. Option B relates to a single variable (cups of water consumed), which doesn’t fit the purpose of a scatter plot since it doesn’t show the relationship between two distinct variables.
