Option A is correct because routines are the Life Sciences Cloud capability intended for reusable visit schedules and recurring route patterns. Salesforce Help describes Customer Engagement features as including the ability to optimize daily schedules by showing key events and applying predefined routines on the calendar. This directly matches the requirement: field sales reps repeatedly visit the same groups of accounts across weekly routes or multi-day coverage patterns and want to reuse those planned schedules instead of rebuilding visits every time.

Routines support practical field planning because a rep can save a predefined pattern of planned visits and apply it later when the same route or schedule is needed. This is different from simply grouping accounts.

Option B is not the best answer because account lists help reps organize, filter, and target groups of accounts, but they do not by themselves preserve a reusable multi-day visit schedule. Account lists can help with planning, but they are not the direct solution for saving and reapplying a planned route. Option C is also incorrect because Activity Plans define strategic goals, targets, and activity expectations across a period. They align engagement activity to business objectives, but they are not designed to save and reapply recurring visit schedules. Therefore, the consultant should recommend creating a routine that saves the predefined set of visits and applying that routine as needed.
