FPSM tasks address both short-term and long-term fault detection and fault assessment.

• A. Short term and Long term
• B. Immediate and Deferred
• C. Local and Global
• D. Sequential and Parallel

Answer: (A)

The idea being tested is that FPSM tasks are designed to handle fault detection and fault assessment across different time horizons. Short-term fault detection and assessment focus on catching and evaluating faults quickly to prevent immediate risk, while long-term fault detection and assessment look at how faults develop over time, informing maintenance planning and life-cycle decisions. This combination ensures both rapid response to near-term faults and a deeper understanding of faults’ progression for future reliability.

That’s why the best answer is short term and long term. The other terms describe timing of actions (Immediate and Deferred), scope (Local and Global), or processing structure (Sequential and Parallel) rather than the time-based horizons involved in fault detection and assessment.
