An outlier is defined as an unusual or extreme value that does not follow the general pattern or distribution of the other observations. It can be identified by being an extreme value for one or more variables, having a residual that is abnormally large in magnitude, or having values for individual explanatory variables that fall outside the general pattern of the other observations. Only option D includes all of these criteria, therefore it is the best choice.
