Studentized residuals are used to identify outliers in regression analysis. Values that are more extreme than -2 or 2 suggest that the corresponding observations may be outliers. Therefore, residuals that fall outside this range (i.e., less than -2 or greater than 2) are typically considered indicative of potential outliers. B is correct

Technically, you are right. I am also confused with the sas contents presenting that In general, studentized residuals that have an absolute value less than 2.0 could have easily occurred by chance. that`s why answer might be C.
