D)random error.
E)none of the above

The central limit theorem states that as the sample size increases, the distribution of sample means or proportions will approximate a normal distribution regardless of the shape of the population distribution. Sample and population variance are related to the spread of data, and random error refers to the unpredictable and unexplainable variability in data.
