Nancy is the project manager of a project with 78 stakeholders.

Communication channels are paths of communication with stakeholders in a project. The number of communication channels shows the complexity of a project's communication and can be derived through the formula shown below: Total Number of Communication Channels = n (n-1)/2 where, n is the number of stakeholders. Hence, a project having five stakeholders will have ten communication channels. Putting the number of stakeholders in the formula we can get the required communication channel for the project. It is (78 x 77)/2 for 3,003 communication channels.

Answer options A, B, and D are incorrect. These numbers do not reflect the accurate number of communication channels in the project.
