Which of the following shows the number of communication channels for a team with twelve stakeholders?

56 is incorrect; this value would result from 8 stakeholders (8 * 7 / 2 = 28), not 12.

The number of communication channels is calculated using the formula n * (n - 1) / 2, where 'n' is the number of stakeholders. For twelve stakeholders, the calculation is 12 * (12 - 1) / 2 = 12 * 11 / 2 = 132 / 2 = 66.

72 is incorrect; this value does not result from the communication channel formula for 12 stakeholders.

132 is incorrect; while 12 * 11 equals 132, the formula requires dividing by 2 to account for unique bidirectional channels.
