C) use comparison groups instead of control groups
D) match groups on any variables that are significant for the fluctuation in the dependent variable

Proceeding with the experiment without addressing the issue of non-equivalence between groups can lead to biased results and flawed conclusions. It is always recommended to take steps to ensure that the groups are as similar as possible before conducting the experiment. Thus, option A should not be used. Instead, options B, C, and D are all valid ways to address the issue of non-equivalence between the groups. Matching the groups on important variables, using comparison groups instead of control groups, and matching groups on any variables that are significant for the fluctuation in the dependent variable can all help to reduce the impact of non-equivalence and increase the validity of the experiment.
