Correct Answer: ABDWhen account teams are enabled, Sales Rep A has the option to grant specific access to Sales Rep B on various aspects of the account. Sales Rep A can grant Read access on the account's cases, which ensures that Sales Rep B can view the details of the cases associated with the account. Additionally, Sales Rep A can allow Sales Rep B to view one of the opportunities on the account. This is helpful for collaborative work while maintaining control over what specific information is shared. While it might seem logical to allow editing of all opportunities, that decision allows too much access and typically requires more restrictive controls. Viewing the account without sharing activities as mentioned in option C isn't generally a common actionable step in team collaboration.
