What should Rhea do after the end of the experiment

A) Have the participants sign a confidentiality agreement.
B) Debrief the participants about the deception.
C) Make sure not to mention the deception to avoid sample bias.
D) Offer the participants a monetary reward in exchange for their suffering.

The best choice would be to debrief the participants about the deception. Debriefing in research is critical as it ensures that the participants are fully informed about the study, including the deception used, and it also allows them to express any concerns or ask questions. By debriefing, Rhea can ensure that the participants understand the nature of the experiment and are not left feeling embarrassed or misled. This step is important in maintaining ethical standards in research. Confidentiality agreements or monetary rewards are not necessary in this case, and not mentioning the deception could lead to biased results.
