If randomization is not possible, a quasi-experimental design should be considered. This type of design allows for comparison between groups, but does not randomly assign participants to groups. Other measures, such as matching or statistical controls, can be used to help reduce potential biases. Pre and posttests and the classical design may not adequately account for differences between groups, making a quasi-experimental design a better option in this scenario. Choice D is incorrect, as there may be limitations or ethical considerations that prevent randomization.
