Flow Builder: Flow Builder can evaluate record criteria using a Decision element and then send an outbound message using the "Action" element. Allows automation without Apex. Approval Process: Approval Processes can evaluate criteria and trigger outbound messages as one of the associated actions. Why Not Other Options? C: Entitlement Process: Focuses on managing entitlements, not triggering outbound messages. D: Next Best Action: Used for recommendations and guided actions, not for triggering outbound messages.
