Which of the following does not need business process?

C.

The correct answer is D. Cases.

Business processes are a way to standardize and automate the steps that users take to work with records in Salesforce. They help to ensure consistency, accuracy, and efficiency in business operations. Business processes are available for several standard objects in Salesforce, including Leads, Opportunities, and Contacts.

Cases, on the other hand, are typically used for tracking customer support issues or other types of work items. While it is possible to create a business process for cases, it is not a requirement. Some organizations may choose to use other tools or methods to manage their case work, or they may not have a formalized process in place for handling cases.

In summary, while Leads, Opportunities, and Contacts all typically require a business process, Cases do not necessarily require one.
