The correct answer is 28 communication channels. To calculate the number of communication channels, we use the formula N(N-1)/2, where N is the number of stakeholders. In this case:

8(8-1)/2 = 8(7)/2 = 56/2 = 28

This formula accounts for the fact that each stakeholder can communicate with every other stakeholder, but we don't count the same connection twice (e.g., A to B and B to A are considered one channel). It's important for project managers to understand this concept as it helps in planning effective communication strategies, especially in larger projects where the number of channels can grow significantly with each additional stakeholder.
