AEfficiency
BReliability
CMaintainability
DPortability
Step-by-Step Solution
Solution:
  1. Step 1: Identify the symptoms

    Slow response and high CPU usage indicate poor resource management.
  2. Step 2: Match symptoms to characteristics

    Efficiency measures how well software uses resources like CPU and memory.
  3. Step 3: Exclude other options

    Reliability relates to failure frequency, maintainability to ease of updates, portability to adaptability across platforms.
  4. Final Answer:

    Efficiency -> Option A
  5. Quick Check:

    High CPU and slow response mean poor efficiency [OK]
Quick Trick: Resource waste means low efficiency [OK]
Common Mistakes:
  • Mistaking reliability for performance issues
  • Confusing maintainability with performance
