Answer:
A) a moderate productivity increase
Step-by-step explanation:
Low cohesiveness means that the group is not united, it is not a team.
Even though the group may be strongly aligned towards achieving the group's goals or the organization's goals, if they cannot work together as a team, then their productivity will not increase a lot. The moderate productivity increase will be due to each individual's alignment with the common goals, so they will work harder to achieve them. But they will work harder on their own, not as a team.
If they were able to work as a team, then the productivity increase would be much greater.
High cohesiveness combined with a strong alignment between group goals and organizational goals typically results strong productivity increases, the key is teamwork.
