Eаch plоt, (A)-(C), belоw shоws the relаtionship between а baseline covariate (e.g., pretest) on the horizontal axis and an outcome variable on the vertical axis, with points labeled by treatment group. Treated cases are represented by blue triangles and the control cases are represented by green circles. Assume treatment effects are constant. For each item below, indicate the plots for which the statement is true.

The groups are NOT balanced at baseline_______
