Choose 1 option.

Option A is the best answer because the requirement is specifically tied to the Next Best Customer user experience. Salesforce Life Sciences Cloud uses Next Best Customer to help sales reps understand and work with the top accounts in their territory by configuring the Next Best Customer component, quick actions, scores, and rationales. Salesforce Help also references Account Scores and Rationales for Next Best Customer as part of the setup path, which confirms that scores and supporting rationale are standard parts of the Next Best Customer capability.

The reps are not asking for a separate generic charting capability or a custom extension. They want to see the data that explains why a customer is recommended and how the score was derived. Embedded charts on the Next Best Customer component meet this requirement because they keep the rationale visualization directly in the same workflow where reps prioritize accounts and plan visits.

Option B is not the best answer because extending the Next Best Customer FlexCard would imply custom development or UI customization when the requirement can be met through the standard component experience. Option C is also not the best answer because the Chart Lightning Web Component Accelerator is a generic charting component, not the Life Sciences-specific Next Best Customer configuration for showing recommendation rationale. Therefore, embedded charts on the Next Best Customer component are the correct recommendation.
