Explanation
Flow Builder is a tool that can be used to create an automated way to delete records based on field values.
Flow Builder can create flows that define the logic and actions for deleting records, such as finding records that match certain criteria anddeleting them in bulk. Flows can be scheduled to run at regular intervals or triggered by other events or processes. References:

The $Record global variable allows you to reference the values of the active record the flow is running on.

Explanation
Role hierarchy and sharing rules are two features that should be used to open up access to Opportunity records for sales users working on collaborative deals. Role hierarchy can be used to grant access to records owned by or shared with users who are belowthem in the hierarchy. Sharing rules can be used to extend sharing access to users in public groups, roles, or territories based on certain criteria, such as record owner or field value.

Explanation
Validation rules are a way to enforce data quality and business logic by preventing users from saving records that do not meet certain criteria. They can be used to require users to follow the status values as they are on the path and prevent them from reverting the case back to a previous status by using formulas that compare the old and new values of the status field. Global value picklists are a way to create and maintain picklist values that can be shared across multiple fields, but they do not enforce any logic or order on the values. Predefined field values are a way to set default values for fields on path settings, but they do not prevent users from changing them later. Dependent picklists are a way to filter the values of one picklist based on the value of another picklist, but they do not prevent usersfrom going back to a previous value.
