Answer and Explanation:
The correct answer is C.

Total number of communication channels can be calculated using the formula [n * (n-1)]/2, where n = number of stakeholders. In our question, we have 20 stakeholders in the project.

Therefore, the number of communication channels = [n * (n-1)]/2 = [20 * (20-1)]/2 = (20 * 19)/2 = 190
