Answer: B- Dr. O’ Malley is obtaining informed consent from his participants while Dr. Quick is debriefing her participants.
Explanation: informed consent is a method whereby a subject willingly makes the decision of partaking in a specific experiment officially acceptable. This is usually given by a doctor or any other person with medical discipline and credentials. However, the informed consent should have all the comprehensive and thorough information concerning the experiment to be carried out and also the chance to stop taking part at any time.
Debriefing is usually administered at the end of an experiment between a doctor and the subject where the information about the theme is communicated, the subject is also given a chance to ask questions.
