An Advantage of Group-Administered Surveys Is That

An advantage of group-administered surveys is that:

A) participants treat the questionnaire more seriously when they fill it out as a group than when they fill it out alone.
B) it is easier to ensure anonymity when participants fill out the questionnaire as a group.
C) you do not have to worry about participants misplacing or forgetting about your questionnaire.
D) participants are likely to be more honest in their responses.
