Explanation

A pending Chatter post is a post that has been scheduled to be published at a future date and time. However, if the user who created the pending Chatter post is deactivated before the scheduled date and time, then the pending Chatter post will be canceled and will not be published. This is because deactivated users cannot create or edit posts in Chatter. References:

The foundation of Salesforce data security is the Organization-Wide Default (OWD). To ensure that users can only see their own records (and those above them in the hierarchy), the administrator must set the OWD for the object to Private. When an object is private, a user can only see records they own. When that user runs a report, the report engine automatically respects these sharing settings and only displays the records the user is authorized to see. This is a much more secure and scalable solution than creating separate reports for every user (Option C). Option A (Public Read/Write) would allow everyone to see everything, violating the privacy requirement. Option D (Apex sharing) is a complex coding solution that is unnecessary when the standard
"Private" sharing model fulfills the requirement through simple configuration.
