In what scenario will a Workflow rule trigger?

A Workflow rule in Salesforce is designed to evaluate records when they are created or edited. This means that whenever there is a change to a record, be it a new record being added to the system or an existing record being modified, the workflow rule will assess whether the conditions defined within it are met. If the criteria are satisfied, the workflow actions such as sending email alerts, updating fields, or creating task reminders will be executed.

While some options suggest that a workflow rule operates under more restricted conditions, or even during deletions, the key function of workflow rules is their responsiveness to changes in data. The comprehensive nature of the correct answer reflects their capability to react to both creation and updates simultaneously, which is essential for managing automated business processes effectively in Salesforce.
