Answer:
Sara should inform/debrief them at the end of her research.
Explanation:
Researchers conducting a study that requires some deception of the subjects may debrief them after the study has been concluded.
Debriefing is a procedure that involves an interview between the researcher and the subjects whereby all elements (about stereotypes in this case) are discussed in detail. Researchers should provide subjects with accurate and appropriate information about the nature of their study or experiment.
