The source control operation used to store local changes on an instance for later application is called a stash. A stash is a temporary storage area for uncommitted changes that are not ready to be pushed to a remote repository. Developers can use stashes to save their work in progress without committing it to the local repository or discarding it. Stashes can be applied later to restore the changes to the working directory, or dropped if they are no longer needed.

The step that does not belong when creating a Utils Script Include is identifying the table. A Script Include is a server-side script that can contain one or more classes or functions that can be reused by other scripts. It does not depend on a specific table, but can access any table through GlideRecord or other APIs. The other steps are part of creating a Script Include class and its prototype object.

Extending an existing table such as the Task table when creating a new application has several benefits, such as:
You can repurpose existing fields by simply changing the label. For example, you can change the Short description field to Summary or Title for your new table.
You can use existing fields with no modifications. For example, you can use the Assigned to, Priority, and State fields for your new table without changing anything.
Existing logic from the parent table will be automatically applied to the new table. For example, you can inherit the Business Rules, Client Scripts, and UI Policies from the Task table for your new table.
The only option that is not true is d) All of the parent table records are copied to the new table. Extending a table does not copy any records from the parent table to the new table. It only creates a new table that inherits the fields and logic from the parent table.

When designing forms in ServiceNow, the primary way to organize fields is by using Sections. Sections let developers group related fields into logical blocks, improving readability and guiding users through data entry in a consistent way. In form configuration tools, sections are structural layout elements that define how fields are arranged and presented, allowing developers to separate a form into meaningful areas such as "Requester Details," "Assignment," and "Resolution." This helps reduce clutter on complex forms and supports usability best practices for enterprise applications. A Button is an action control and does not organize fields. A Related list shows records from other tables that are related to the current record; it supports navigation and context, but it does not organize the main record's fields. Formatters are specialized UI components that can display additional information or UI elements on a form, but they are not the standard feature for grouping and organizing fields in the form layout. Because the question asks specifically about organizing fields during form design, Section is the correct choice.
