Which of the following actions is considered acceptable for a real estate agent?

Providing full disclosure to clients is a fundamental responsibility of a real estate agent and is considered both ethical and legal in the practice of real estate. Full disclosure ensures that clients have all relevant information regarding a property, including its condition, history, and any potential issues. This transparency fosters trust between the agent and the clients and helps clients make informed decisions.

In contrast, refusing service based on ethnicity is discriminatory and violates fair housing laws. Charging higher fees to certain clients can signify unethical practices and discrimination as well. Selling properties without inspections can expose buyers to unknown issues with the property, which contradicts an agent's duty to protect their clients' best interests. Overall, ensuring clients are fully informed aligns with both ethical standards and legal obligations within the real estate profession.
