Software does not wear-out in the traditional sense of the term, but software does tend to deteriorate as it evolves, because

Software suffers from exposure to hostile environments. Defects are more likely to arise after software has been used often Multiple change requests introduce errors in component interactions. Correct Software spare parts become harder to order

Software Deterioration and Entropy (Pressman):
Physical hardware wears out due to physical friction, heat, and environmental fatigue.
Software does not suffer physical wear-out; however, it deteriorates over time as it evolves because:
Repeated maintenance cycles, bug patches, and new feature requests introduce architectural entropy.
Unanticipated side effects and dependencies emerge between interacting components, increasing complexity and error rates.
Conclusion: Multiple change requests introduce errors in component interactions (Option 3).

Correct option: (3) Multiple change requests introduce errors in component interactions.
