We can use the Critical Path Method (CPM) to determine the total time to complete the project and the latest finish time for the last activity. 
- First, we draw the network diagram and identify the critical path (the longest path) which is A-B-E-F-G:
A (0) -> B (2) -> E (4) -> F (8) -> G (11)
- The latest finish time for the last activity (G) is the same as the total time to complete the project, which is the sum of the durations of the activities on the critical path:
0 + 2 + 4 + 8 + 11 = 25
- Therefore, the latest finish time for activity G (and the total time to complete the project) is 11 days. 
- The other answer choices (A, B, D, E) are not correct because they are either too short or too long based on the time estimates for the activities on the critical path.
