In Salesforce Flow, to post to a Chatter feed and mention the record owner, the Post to Chatter action can be used with a message input. Mentions are added using the syntax:

@[{!User.Id}] or simply @[reference], where the reference points to a user ID.

This enables the Chatter post to tag the record owner by dynamically inserting their user ID into the message.

Incorrect Options:

A. There is no concept of “flow directives”; this terminology is incorrect.

B. Assignment is used to assign values to variables but not to create a Chatter mention.

C. Creating shadow records is not necessary and overly complex for this use case.

Reference Extracts from Salesforce Help - Automate Posts to Chatter Using Flow:

“Use the Post to Chatter action to send a message to a record's feed. Mention users by entering @[userId].”
