How would we go about doing this question?

13. Which of the following pairs of sample size n and population proportion p would produce the greatest standard deviation for the sampling distribution of a sample proportion p ? (A) n = 1,000 and p close to O (B) n = 1,000 and p close to 1 (C) n = 1,000 and p close to N/ - (D) n = 100 and p close to O (E) n = 100 and p close to N/
