You don't communicate to convey activities, or to integrate activities. We can, therefore, eliminate answers "a," "b," and "e."
So is our purpose to discuss or organize an activity? Either answer fits. We discuss activities to gather the opinions of others regarding said activities. But discussing is, itself, a form of communicating, it is not an outcome. The other points listed are outcomes "we provide... influence... [through communication]." Therefore, the answer must be "c. organize".
