ANCOVA can be modeled as a linear multiple regression with the independent variables reduced to dummy variables. This is because ANCOVA involves comparing group means while controlling for a covariate, which can be achieved through dummy variables in a linear regression model. The other options are not appropriate alternatives for modeling ANCOVA.
