Which of the following confidence intervals will have a smaller margin of error?

A. A 99% confidence interval for the mean score of women. Sample size = 50
B. A 95% confidence interval for the mean score of women. Sample size = 100
C. A 95% confidence interval for the mean score of men. Sample size = 50
