Explanation
Flow builder and approval process are two tools that can be used by Ursa Major Solar to assist users with a guided expense report process to simplify submissions, routing, and authorizations. Flow builder is a tool that allows administrators to create flows, which are guided processes that collect data and perform actions in Salesforce; it can be used to create a screen flow that guides users through the steps of submitting an expense report, such as entering expense details, uploading receipts, etc. Approval process is a tool that allows administrators to create approval processes, which are automated processes that require approval from one or more approvers; it can be used to create an approval process that routes expense reports to the appropriate managers for authorization basedon certain criteria, such as amount, type, etc. Validation rule, quick action are not tools for building a guided expense report process; they are used for different purposes such as enforcing data quality or creating records.

Explanation
To route new leads to the correct sales person based on the lead address, the administrator should use lead assignment rules that specify criteria based on lead fields such as City, State/Province, or Country, and assign leads that match those criteria to queues or users. Lead assignment rules can be triggered automatically when leads are created or manually by users. Creating a formula field, assigning with an escalation rule, or configuring a validation rule will not route leads to sales people. References:
