Given the tasks listed below: - Task A has a duration of five days and successors of Tasks B and C. - Task B has a duration of two days and a successor of Task D. - Task C has a duration of one day…

The correct answer is C. A, B, D. The critical path is the longest sequence of dependent tasks that determines the minimum project duration. Two paths exist: Path 1: A → B → D = 5 + 2 + 3 = 10 days. Path 2: A → C → D = 5 + 1 + 3 = 9 days. Path 1 (A, B, D) is the longest at 10 days and is therefore the critical…

Explanation

The critical path is the longest sequence of dependent tasks that determines the minimum project duration. Two paths exist: Path 1: A → B → D = 5 + 2 + 3 = 10 days. Path 2: A → C → D = 5 + 1 + 3 = 9 days. Path 1 (A, B, D) is the longest at 10 days and is therefore the critical path. Any delay on tasks A, B, or D will directly delay the project finish date. Task C sits on the non-critical path - it has 1 day of float (slack) and can be delayed by up to 1 day without impacting the overall schedule. Answer C (A, B, D) correctly identifies the critical path.
