OPTIONS:

a. When there are just two other people at the party.

b. When everyone is wearing a nametag.

c. When there are more than 50 people attending the same party.

d. When the need for help from the person who is having a heart attack is very clear

Answer:

c. When there are more than 50 people attending the same party.

Explanation:

Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.

In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.

The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>
