To calculate slack time, we need to first calculate the earliest start time (EST) and latest start time (LST) for each activity.

For Activity B:
EST = 2 (since it can start immediately after Activity A, which takes 2 units of time)
LST = 8 (since it must finish before Activity F, which starts at 10 and takes 2 units of time)

Slack time = LST - EST = 8 - 2 = 6

Therefore, the answer is B. Activity B has a slack time of 6 units.
