C)population size increases
D)none of these

As the degrees of freedom (df) of the sample increase, the sample size increases as well, which leads to a decrease in sampling error and an increase in the accuracy of the estimate. Therefore, increasing the df typically leads to a more accurate estimation of the population parameter. The population size is generally irrelevant to the accuracy of estimation, as it is the sample size that matters in most cases. Decreasing the df (i.e., decreasing the sample size) typically results in less accurate estimation because the sample may not be representative of the population.
