The correct answer is A because Salesforce Life Sciences Cloud provides the MIRF Share Management job specifically to manage sharing for medical inquiry records. Salesforce Help states that teams can save time, reduce manual errors, and maintain the integrity and reliability of inquiry data by using the MIRF Share Management job. Salesforce also has dedicated guidance for defining sharing settings for Medical Inquiries.

The requirement is territory-based sharing: all medical inquiries in a territory must be shared with all field sales reps in that same territory. A scheduled MIRF Share Management job is the Life Sciences-specific mechanism designed to maintain this sharing behavior for medical inquiry records. This is preferable because medical inquiry workflows often have regulated data-handling and access-control requirements, so using the purpose-built sharing-management capability is safer and more maintainable than creating generic sharing automation.

Option B is not the best answer because the described configuration is not simply a generic Territory Management setting in the Life Sciences Admin Console. The question asks specifically how to share medical inquiry records, and Salesforce points to MIRF Share Management for that purpose. Option C is also incorrect because an owner-based sharing rule on the Inquiry object would be a generic Salesforce sharing approach. It may not correctly reflect Life Sciences medical inquiry sharing logic or maintain the intended record integrity. Therefore, the consultant should schedule the MIRF Share Management job.
