Virginia Code § 38.2-3502 mandates a “free look” period (typically 10 days) for individual health insurance, allowing the insured to review the policy and cancel it with a full premium refund (option D) if returned within that time. Option A (try without paying) is false; premiums are paid upfront, refundable only upon cancellation. Option B (compare policies) is a practical use but not the legal purpose; the provision ensures cancellation rights, not comparison. Option C (change coverage) isn’t allowed; modifications require underwriting, not free-look terms. The study guide likely details this consumer protection with examples—e.g., returning a policy on day 9 for a refund—making D the precise right.
