Random assignment ensures that participants are distributed equally across experimental conditions, minimizing the potential influence of extraneous variables. All participants being the same in terms of ethnicity, age, sex, etc. is not necessary and can even limit the generalizability of the findings. Observing participants in natural settings may be appropriate for some studies but is not necessary or appropriate for all studies. Therefore, the best choice is A - randomly assigned to experimental conditions.
