While Internet Research Can Create Difficulties in Effectively Debriefing Research

While Internet research can create difficulties in effectively debriefing research participants, there are several options researchers can use to increase the chances that debriefing is available for participants who terminate the study early. Which of the following is NOT one of these options?

A) Have the participant provide an email address so that a debriefing statement can be sent to them
B) Put the debriefing statement at the end of the experiment
C) Provide a "leave the study" radio button on every page that will direct the participant to a debriefing page
D) Incorporate a debriefing page into the program driving the study that automatically directs them to the debriefing page if they terminate the study early
