Final answer:
An appraiser may never recommend a specific home inspector as it could suggest a conflict of interest or bias, undermining their required professional standards and ethical obligations.
Step-by-step explanation:
The individual who may never recommend a specific home inspector is B) An appraiser. Appraisers must maintain objectivity and independence in their assessments of a property's value.
Recommending a specific home inspector could imply a conflict of interest or the appearance of bias, which could undermine the professional standards and ethical obligations appraisers are required to uphold.
In contrast, a buyer's agent, the seller, and a dual agent might have more leeway in suggesting inspectors, though with dual agents, caution is advised due to their complex role.
