Final answer:
The most efficient way to move from an Account record to a related Contact record is by using the Related List feature in a CRM system, allowing direct access to related records.
Step-by-step explanation:
To most efficiently move from an Account record to a related Contact record in a database or customer relationship management (CRM) system, Option 2: Related List would be the best choice. Related Lists are a feature in CRM systems that allow users to see a list of records that are connected to the record they are currently viewing, eliminating the need for a separate search or navigation step. When viewing an Account record, a user can simply scroll down to the Contacts section where the related Contacts are listed and click on a Contact's name to navigate to their record directly.
