Which term describes adjustments to address faults in a product?

• A. Modification
• B. Optimization
• C. Validation
• D. Synthesis

Answer: (A)

Adjustments to address faults in a product are actions taken to change or alter the design or components to fix problems. This idea fits the term modification, which is about making changes to correct faults or poor performance after testing or feedback. It’s different from optimization, which aims to push performance or efficiency to the highest level regardless of fault correction; validation, which is about proving the product meets requirements; and synthesis, which is about combining elements to create something new. So when the goal is to fix issues by altering the product, modification is the most direct and appropriate description. For example, swapping a problematic part or redesigning a feature to prevent failure is a modification aimed at addressing faults.
