SolutionC is correct. The sampling distribution of a statistic (like a sample mean) is defined as the probability distribution of a given sample statistic when samples of the same size are randomly drawn from the same population.
A is incorrect. Discrete uniform distribution refers to the distribution of equally likely outcomes.
B is incorrect. Multivariate normal distribution specifies the probabilities for a group of related random variables.
