Explanation:

To determine the best statistical question about roller - coaster riding habits, we analyze each option:

• Option "Did you ride a roller coaster today?" is a yes/no question and gives limited data about habits.
• Option "How fast is the coaster you rode today?" focuses on the speed of the coaster, not the riding habits (like how many times one rides).
• Option "How many times did you ride a coaster today?" directly relates to the riding habit (frequency of riding) and will give numerical data suitable for statistical analysis.
• Option "How many roller coasters are there at this park?" is about the number of coasters in the park, not riding habits.

Answer:

C. How many times did you ride a coaster today?
