What types of systems and components must the inspector examine during an inspection?

The selection of examining all readily accessible, visually observable installed systems and components is correct because it aligns with the comprehensive nature of a home inspection. A thorough inspection involves evaluating various systems and components to provide a complete assessment of the home's condition.

Home inspectors are trained to assess a wide range of elements, including roofing, plumbing, electrical systems, HVAC, structural integrity, and more. This approach ensures that any potential issues are identified, which is essential for informing potential buyers about the overall state of the property. By examining all accessible installed systems and components, inspectors can offer a clearer picture of the property's condition, allowing buyers or homeowners to make informed decisions regarding maintenance, repairs, or negotiations.

Focusing on only specific types of systems can lead to oversight of critical issues elsewhere, ultimately compromising the integrity and value of the inspection report. Additionally, limiting the inspection to systems that are suspected of being faulty would omit valuable preventive insights and could leave significant hidden problems unaddressed. Thus, the inclusive approach of option B is fundamental to effective home inspections as mandated by professional standards.
