C)The sampling distributions of the estimators follow the chi-square model.
D)All of the above are true.

Question

The sampling distributions of the estimators for the slope and intercept of a regression line, under the conditions of the linear model, follow a Normal distribution, not a chi-square distribution. This makes statement C incorrect. The estimators are indeed unbiased, and they do follow the Normal model when the conditions for linear regression are met.
