The abstract of the original paper gives a 95% confidence interval of [0.3, 0.8] for the relative risk. Which of the following statements can be justified based on that confidence interval?

A. There is a 95% chance the relative risk is between 0.3 and 0.8.
B. If we used a P-value cutoff of 5%, we would reject the null hypothesis that HRT does not affect the risk of CHD.
C. If we redo the procedure that generated the interval [0.3, 0.8] on a fresh sample of the same size, there is a 95% chance it will include the true relative risk.
D. There is between a 30% and 80% chance that any woman will suffer a heart attack during the study period
