Non-equivalent groups design can be used when it is not possible to create groups through randomization. In this design, the groups are not selected randomly, but they are selected based on some criteria like age, gender, or other vital factors that affect the study. This design helps in examining the impact of the independent variable on the dependent variable by comparing the pre-existing groups. Hence, it is the best choice when randomization is not feasible.

Options A, C, and D are not the best choice because they do not address the problem of not being able to create groups through randomization. A classical experiment requires groups to be randomized. Surveys and pre and post tests may not provide the necessary comparison between groups that are necessary to determine the effect of the independent variable on the dependent variable.
