Virginia Code § 38.2-5207 and 14VAC5-200-185 outline marketing standards for long-term care (LTC) insurance to protect consumers. Option A (twisting)—misrepresenting a policy to induce replacement—is prohibited as an unfair practice (Virginia Code § 38.2-502). Option C (high pressure tactics)—aggressive sales forcing quick decisions—violates ethical standards and is banned (14VAC5-200-40). Option B (replacing existing coverage) is incorrect as stated; replacement itself isn’t prohibited but requires disclosure via a replacement notice (14VAC5-200-75), making it regulated, not banned outright—however, the question implies unauthorized or deceptive replacement, which is prohibited. Option D (cold lead advertising)—soliciting via broad, unsolicited leads (e.g., mailers)—is permitted if it complies with disclosure rules and isn’t deceptive (14VAC5-200-50). The study guide likely lists twisting and high pressure as unethical, with examples like misstating benefits, while allowing cold lead ads with proper labeling (e.g., “advertisement”), making D the exception.
