Exam ALS-Con-201 Topic 2 Question 21 Discussion

Option A is correct because Salesforce Help for setting up the Inquiry record page for Medical Inquiries explicitly states that, to view timeline details for inquiries, the consultant should drag the Timeline component to the page. The requirement in the question is to expose a chronological list of key events and changes associated with the inquiry. That is exactly the purpose of the Timeline component on the Medical Inquiries record page.
Salesforce also documents Enhanced Timeline for Life Sciences Cloud, explaining that the Enhanced Timeline component shows key events relating to a person or a record. This supports the use case of giving users a consolidated, chronological view of relevant inquiry activity, rather than requiring them to inspect multiple related lists or audit records separately.
Option B is not the best answer because field history tracking and the standard History component are used for field-level audit history, not the Life Sciences Medical Inquiries timeline experience. Option C is also incorrect because adding an Inquiry History related list would expose related records, but it would not provide the configured timeline component experience described in Salesforce's Medical Inquiries setup documentation.
Therefore, the consultant must drag the Timeline component onto the Lightning record page and configure its component details for the Inquiry record page.
