In a study of bystander intervention, Darely and Lantane had participants take part in a discussion via an intercom system. The participants were alone in a room and could only communicate with others through the intercom system. The experimenters manipulated the number of people the participants thought were a part of the discussion. During the discussion,,one of the participants (a recording) had an epileptic seizure. Those participants who thought there were three other people as part of the group were:

A) more likely to help compared to when they thought they were the only person who heard the seizure.
B) less likely to help compared to when they thought they were the only person who heard the seizure.
C) less likely to help compared to when they thought six other people heard the seizure.
D) just as likely to help as when they thought two other people heard the seizure.
