Describe what you observe with the RMSE as the size of the dataset becomes larger.

A. On average, the RMSE does not change much as n gets larger, while the variability of RMSE does decrease.

B. Because of the law of large numbers, the RMSE decreases: more data, more precise estimates.

C. n = 10000 is not sufficiently large. To see a decrease in RMSE, we need to make it larger.

D. The RMSE is not a random variable.
