What is a workflow rule in Salesforce?

A workflow rule in Salesforce is an automated process that triggers actions based on specific criteria. This means that when certain conditions are met within the Salesforce environment, a workflow rule can automatically initiate predefined actions such as sending email alerts, assigning tasks, updating fields, or creating outbound messages. The criteria can be based on various record fields and can help streamline business processes by facilitating timely interventions without the need for manual user actions.

Through workflow rules, organizations can enhance their efficiency by automating routine tasks and ensuring that processes are followed consistently. The ability to respond automatically to changing information or specific events allows sales teams to focus more on customer engagement rather than administrative tasks.

While other options mention aspects like manual input, user permissions, and data storage, these do not accurately capture the fundamental purpose and function of a workflow rule within Salesforce. Workflow rules specifically focus on automation based on conditions, making option B the most descriptive and accurate choice.
