What describes resource leveling and its potential trade-off?

• A. Adjusting resource allocation across activities with no effect on time.
• B. Shortening a task duration to save time, which always reduces the project duration.
• C. Adjusting activity start times to address resource over-allocations; it may extend the project duration or alter the critical path.
• D. Reassigning resources only on noncritical tasks with no schedule impact.

Answer: (C)

Resource leveling is about smoothing how resources are used by shifting the start times of activities to resolve over-allocations. The key trade-off is that, to fix these conflicts, the overall project schedule can be lengthened and the critical path may change as tasks are delayed. This technique focuses on timing adjustments, not shortening task durations. Reallocating resources can involve noncritical tasks, but it can still impact the schedule and which activities drive the finish.
