Correct option is B
The Critical Path Method (CPM) is best suited for projects where time estimates are relatively certain and task dependencies are clearly defined. Among the given scenarios, designing a prototype with clear task dependencies aligns with CPM principles because it involves well-defined activities, predictable durations, and logical sequencing, allowing the identification of the critical path to manage the project schedule effectively. Projects with frequent changes, unpredictable markets, or unknown outcomes are better handled with flexible or probabilistic methods like PERT.
