Final answer:
The response to the 9/11 terrorist attacks with aid and support is an example of a tend-and-befriend response, which involves collective actions for protection and solidarity during times of stress. The answer is option B.
Step-by-step explanation:
After the terrorist attacks of 9/11, the nationwide response of people going to New York City to lend aid is an example of a tend-and-befriend response. This term refers to how individuals might seek out social support and opportunities to help others in times of stress, which is precisely what was observed following the events of September 11. In contrast to fight-or-flight reactions, which are more individually focused, tend-and-befriend is characterized by collective and nurturing actions meant to protect oneself and others by forming and maintaining social bonds.
Following 9/11, many Americans displayed their national solidarity through acts of kindness, such as donating to relief efforts, giving blood, or volunteering, as opposed to retaliatory or individualist reactions. This massive show of charitable action and volunteerism represented an overwhelming wave of social support that is typical of a tend-and-befriend response in the face of collective trauma.
