B)t value
C)standard error
D)square

The standardized residual is obtained by dividing the residual of a particular observation by its standard error. This is because the standard error measures the variability of the residuals and is used to put the residual on a common scale so that we can compare them across different observations. Dividing by the square or t value is not necessary for calculating standardized residuals. The sample size is also not directly relevant to calculating standardized residuals.
