Given the following activity duration table, what is the critical path length? | Activity | Predecessor | Duration (days) | |---|---|---| | A | - | 5 | | B | A | 7 | | C | A | 3 | | D | B | 4 | | E | C | 6 | | F | D, E | 2 |
- A.16 days (A→C→E→F)
- ✓ Correct B.18 days (A→B→D→F)
- C.14 days (A→B→F)
- D.20 days (A→B→C→E→F)
Correct answer: B
Explanation
The correct answer is B. Path A→B→D→F = 5 + 7 + 4 + 2 = 18 days, and path A→C→E→F = 5 + 3 + 6 + 2 = 16 days. The critical path is the longest, A→B→D→F, at 18 days. 16 days (A) is the shorter path, A→B→F (C) skips predecessor D, and A→B→C→E→F (D) is not a valid sequence because C depends only on A.
