ANCOVA can be modeled as a linear multiple regression with the independent variables reduced to dummy variables. This approach allows for the inclusion of both categorical and continuous independent variables, as well as a covariate, in the analysis. Standardizing the dependent variables and covariate (as suggested in option B) is not necessary for ANCOVA, and logistic regression (options C and D) is not appropriate for analyzing continuous dependent variables.
