Which scenario will a Scheduled Script Execution (Scheduled Job) be implemented?

Scheduled Script Executions (formerly known as Scheduled Jobs) are used to run server-side logic at specific intervals, such as querying or updating records automatically. Option B describes a valid server-side scheduled use case.

From ServiceNow Docs (https://developer.servicenow.com/ ):

“Scheduled Script Executions allow you to define JavaScript logic that runs on a schedule to automate tasks such as checking data integrity, generating reports, or reassigning records.”

Client-side logic like in options A, C, and D must use Client Scripts or UI Policies, not Scheduled Jobs.
