Activity E has the greatest amount of slack because it is not on the critical path. The critical path is A-C-D-F with a length of 7+8+3+8=26 days. Activity E, with a length of 2 days and only depending on B (which itself depends on A), does not extend the overall project duration, thus allowing it the greatest slack compared to activities directly on the critical path.
