During a walk-through, Salesperson Kendall notices a stain on the kitchen ceiling, suggesting the seller consult an appropriate expert. Who is NOT an appropriate expert in this situation?

In this scenario, the issue observed by Salesperson Kendall is a stain on the kitchen ceiling. This type of stain typically indicates a potential problem with the plumbing system, such as a leak. Therefore, the most appropriate expert to address this issue would be someone with knowledge and expertise in plumbing, like a building inspector or a home inspector.

Option C, a painting and refinishing contractor, is not the most suitable expert to consult in this situation. While a painting and refinishing contractor may be skilled in addressing cosmetic issues like painting over the stain, they may not have the expertise to diagnose and repair the underlying plumbing issue causing the stain. Hence, they are not the most appropriate professional to recommend in this case.
