How many components must be tested?

• A. 20
• B. 60
• C. 40
• D. 100

Answer: (C)

The main idea here is that lead inspections follow a defined sampling plan that specifies how many components must be tested to get a representative view of any lead hazards. The goal is to test enough different surfaces and areas to reliably detect lead-based paint across the structure while avoiding unnecessary testing. Why this option fits: it reflects the standard that sets a practical, sufficient number of components to sample so you don’t miss hazards by under-sampling, yet don’t waste time by over-sampling. Testing too few components can leave hazards undiscovered; testing more than the plan requires typically doesn’t improve reliability enough to justify the extra effort. The chosen count adheres to the inspection protocol’s guideline for an effective, representative assessment of typical building components and locations. In practice, the other counts would either under-sample and risk missing lead hazards or over-sample and waste time, which is why the option that matches the established sampling guideline is the correct one.
