Using the term 'Realtor' without the legal right to do so is considered?

Using the term 'Realtor' without the legal right to do so is considered a violation of state law. This is because 'Realtor' is a trademarked term that can only be used by members of the National Association of Realtors (NAR). Therefore, using the term without being a registered member can result in legal consequences. Options B, C, and D are incorrect because using the term 'Realtor' without legal permission is not ethical, not a marketing strategy, and not acceptable under any conditions. It is important to abide by trademark laws in order to avoid any legal issues.
