25. Marianne has been a great client and her agent, Doug, is wondering if Marianne can refer him to other Medicare beneficiaries. Doug is considering giving Marianne a gift card as a thank you. Is he allowed to do this? O A. Doug can give Marianne the gift card as long as the gift card has a value of $15 or less O B. Although Doug can give Marianne the gift card (for $15 or less), it also may be tied to his need to directly solicit leads or enrollments, so this is not a good idea O C. Doug can give Marianne the gift card only when the referred beneficiary enros in the plan he is selling
