C) Making sure to have a control group
D) Random assignment of the treatment

The assumption of no correlation between the error term and treatment(s) is similar to the assumption of random assignment of the treatment in the scientific method. Random assignment helps to ensure that treatment groups are similar across all variables, except for the one being manipulated, which minimizes the potential for confounding variables to influence the results. Similarly, assuming no correlation between the error term and treatment(s) helps to ensure that any observed effects are due to the treatment(s) and not some other variable or confounding factor.
