The correct answer is B because the requirement is product-specific consent tracking. Salesforce's Life Sciences Consent Management data model is designed for capturing and managing HCP consent and communication preferences. The model includes objects such as Communication Subscription, Communication Subscription Consent, Contact Point Consent, and Life Science Marketable Product, which together support consent management across communication channels and products.
When a field sales rep captures whether an HCP agrees to receive communications for a specific product, the consent must be tied both to the communication/contact point consent and to the relevant Life Sciences Marketable Product. A Life Sciences Marketable Product Consent record provides that product-level association, allowing the organization to track consent preferences for a particular product rather than only a general channel or subscription.
Option A is incorrect because Data Use Purpose represents the purpose for using data, such as marketing or communication, but it does not by itself create a product-specific consent relationship between an HCP's contact point and a marketable product. Option C is also incorrect because adding a custom lookup to Communication Subscription Consent would be unnecessary and less aligned with the standard Life Sciences consent model. The best-practice configuration is to use the standard product-consent relationship by creating a Life Sciences Marketable Product Consent record linked to the relevant Contact Point Consent and product.
