Step-by-step explanation:
The statement that is true among the options provided is C. Individual productivity is necessary for group productivity. This statement highlights that for a group to be productive and achieve its goals, each individual member must also be productive. It aligns with the idea that collective action problems are less severe in smaller groups because individuals have a more difficult time free-riding and their behavior can be more effectively monitored. In small groups, peer pressure to contribute can also play an important role, as there is often a closer interpersonal relationship and accountability.
The responsibilities of an individual in a group include contributing to the group's goals, participating actively, and fulfilling agreed-upon tasks. Individual freedom within a group is necessary as well because it allows members to bring diverse ideas and approaches to the table, which can lead to innovation and improved problem-solving. However, too much individual freedom can lead to a lack of cohesion and collective action problems, such as the free rider problem or the tragedy of the commons.
In summary, individual contributions are critical to group success, just as economic efficiency is important to maximize the benefits from scarce resources both on a group and individual level.
