Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

15 days

The critical path is the longest path through the network. Path A-B-D-E-G = 3+4+5+2+1 = 15 days. Path A-C-D-F-G = 3+2+5+3+1 = 14 days. Therefore, the critical path duration is 15 days. Options B, C, and D are incorrect because they do not represent the longest path duration.
