What is a joint action by a group of people where each person sets aside their own individual interests and works towards the goals of the group?

The correct answer is teamwork. Teamwork is defined as a collaborative effort by a group of individuals who work together towards shared objectives, prioritizing the group's goals over personal interests. This collective approach helps to harness the strengths, skills, and talents of each member to achieve outcomes that may be greater than any individual could accomplish alone.

In teamwork, communication and cooperation are vital as team members rely on one another to contribute effectively. The essence of teamwork lies in unity and a common purpose, fostering an environment where members support each other to reach their objectives.

Other choices highlight important concepts but do not capture the essence of the collaborative spirit found in teamwork. Leadership refers to guiding and influencing others but may not necessarily mean sacrificing individual interests for the group. Competition involves striving against others for a goal, which is contrary to the collaborative nature of teamwork. Coordination involves organizing activities among individuals but does not inherently involve the collective prioritization of group goals over personal interests. Thus, teamwork is the accurate description of the scenario presented.
