If we have no knowledge of the approximate values of the sample proportion, we can assume the worst-case scenario, where p = 0.50 (50/50 chance). This is the safest assumption to make, as it will result in the largest possible sample size, which will provide a more accurate estimate of the true population proportion. Therefore, we can choose option C, which says to let p = 0.50.
