The standard error of the mean is defined as the standard deviation of the sampling distribution of the mean. Its formula is s/sqrt(n), where s is the sample standard deviation and n is the sample size. Option A is the population standard deviation, option B is the sample mean, and option D is the sample standard deviation, none of which is the formula for the standard error of the mean. Therefore, the correct choice is C.
