Final answer:
A buyer's agent should not provide legal services to the principal unless they are licensed attorneys. They can offer financial and appraisal services relevant to property purchasing.
Step-by-step explanation:
A buyer's agent should not provide which of the following services to the principal? The correct answer is B) Legal services. While buyer's agents are responsible for assisting clients in finding and acquiring property, they are not allowed to provide legal advice unless they are licensed attorneys. Offering legal services without the requisite legal qualification could be a breach of state law and professional ethics. Buyer's agents can, however, provide financial and appraisal services within the scope of their expertise, often helping with property valuation and financial advice related to the purchase.
