Independence of errors is a key assumption of the regression model, as it ensures that the observations are not influenced by each other and that the regression coefficients are accurately estimated. The other choices are incorrect because normality of errors and non-zero standard deviation are desirable but not necessary assumptions, and regular variance of errors is assumed but not zero variance.
