A study was conducted in men aged 40-70 in order to determine whether exercising for 2 or more hours per week decreases the likelihood of heart attack. The cases were 1,000 men who had recently had a heart attack; of these, 236 reported that they had regularly exercised for two or more hours per week prior to their heart attack. 1,000 controls were also selected for the study; of these, 379 reported that they exercised regularly. Calculate the magnitude of association between regular exercise and heart attack. What does your calculation suggest? (Select one answer.)
A. People who exercise regularly have about a 50% chance of having a heart attack.

C. People who exercise regularly have about 0.5 times the risk of having a heart attack compared to people who don't exercise.
D. People who exercise regularly have about 2.0 times the risk of having a heart attack compared to people who don't exercise.
