Monte Carlo Analysis.

Project Management Information System (PMIS).

Earned Value Management (EVM).

Integrated Project Plan.

AMonte Carlo analysis is a simulation technique used to assess uncertainty and schedule risk. It runs many possible scenarios using probability distributions for activity durations, costs, or other uncertain variables. The result is a range of possible completion dates, confidence levels, and risk exposure rather than a single deterministic schedule. A Project Management Information System is a tool for managing project information, not a simulation methodology. Earned Value Management measures project performance against cost and schedule baselines. An integrated project plan organizes scope, time, cost, quality, resources, and risks, but it is not the simulation technique described. Internal audit may review Monte Carlo results when evaluating whether project schedule estimates appropriately consider uncertainty. Therefore, Option A is correct.
