The formula for calculating the standard error of the mean (SE) is SE = σ/√n, where σ is the standard deviation of the population and n is the sample size. Here, σ = 36 and n = 4. Substituting these values in the formula, we get SE = 36/√4 = 36/2 = 18. Therefore, the standard error for the distribution of sample means is 18, which corresponds to choice C.
