Which workflow action might cause this behavior?

UVC wants to automate a business process using workflow. They are aware that workflow rules may cause recursive behavior, and as a result certain actions will only cause workflow rules that didn’t fire previously to be retriggered .

Which workflow action might cause this behavior?

B . Workflow Field Updates with the “Re-evaluate Workflow Rules After Field Changes” field selected
C . Workflow Emails containing hard coded links with Salesforce IDs referencing specific workflow rules
