The residual plot shows a random scatter around 0, indicating that the linear regression model is a good fit. The scatterplot of the residuals against the predicted values shows no pattern, indicating that the Independence assumption is satisfied. The histogram is approximately bell-shaped, indicating that the Nearly Normal condition is reasonably satisfied. Therefore, the best choice is C.
