The correct answer is B because the requirement is to send Medical Insights to an external system without delay, which points to an event-driven integration pattern. Salesforce's Life Sciences Cloud Developer Guide defines MedicalInsight as important information observed or heard through outlets such as meetings, calls, or research and used to inform strategy or follow-up. For near-real-time downstream processing, the appropriate Life Sciences configuration is to publish the standard Medical Insight platform event by activating the handler designed for that purpose.

Activating PublishMedicalInsightEventHandler allows newly captured Medical Insight data to be published as a MedicalInsightEvent platform event. Platform events are the correct Salesforce pattern when an external system needs to subscribe and react quickly as records are created or changed. This avoids waiting for scheduled jobs, exports, or manual data transfers, and it supports timely intelligence generation from field-captured insights.

Option A is incorrect because creating a custom platform event is unnecessary when the Life Sciences feature provides a standard MedicalInsightEvent mechanism. Custom events add avoidable implementation and maintenance complexity. Option C is also incorrect because MedicalInsightIntegrationHandler is not the specific handler described for publishing the MedicalInsightEvent platform event. The key words in the question are ''without any delays,'' which make an event-based publishing configuration the best fit. Therefore, the consultant should activate PublishMedicalInsightEventHandler.
