Validation Rules

To require users to follow the status values as they are on the path and
prevent them from reverting back to previous status values, the administrator should use validation rules that check if the statusfield value is changed from one value to another value that is not allowed by business logic. For example, if status values are New > In Progress > Closed, then a validation rule can check if status is changed from Closed to In Progress or New, and show an error message if true. Predefined Field Values, Global Value Picklists, and Dependent Picklists are not able to enforce status progression or prevent status
reversion.

Create and assign a custom profile with Delete access removed for eachobject.

A custom profile is a profile that can be created and customized by
administrators to define what users can see and do in Salesforce based on their job function or role. It can be used by Cloud Kicks to give read, create, and edit access for objects and restrict users from deleting any records by creating and assigning a custom profile with delete access removed for each object in the object settings. Assigning the standard system administrator profile to analytical user, giving user view all access and assigning them to highest role in role hierarchy, or creating and assigning permission set that includes read, create, and edit access are not solutions for giving read, create, and edit access for objects and restricting users from deleting any records; they either give too
much access or do not remove delete access.

Assignment Rules

Assignment rules are tools that allow administrators to automatically route records to users or queues based on certain criteria. For example, anassignment rule can assign cases to different queues based on case priority, origin, type, or other fields. Assignment rules can be triggered when records are created manually, via email, web, or API. Assignment rules consist of multiple rule entries that define the criteria and actions for each assignment scenario.

Themaster object can be a standard or custom object.

B.

Permissions for the detail record are set independently of the master.

C.

Each object can have up to five master-detail relationships.

master-detail relationship is a parent-child relationship in which the master
object controls certain behaviors of the detail object. The master object can be a standard or custom object, but not all standard objects support being a master. Roll-up summaries are fields that calculate the sum, count, min, or max of child records. The owner field on the detail records is not available and is automatically set to the owner of the master record.
