In ServiceNow, UI Actions are elements that make the user interface more interactive and tailored to user activities. They can appear as buttons, links, or context menu items on forms and lists. The valid types of UI Actions include:
* C. Form choice: These are UI Actions that appear as choices in form context menus, allowing users to perform specific actions related to the form.
* D. Form button: These are buttons that appear on forms, enabling users to execute defined actions directly from the form view.
* E. List banner button: These are buttons that appear in the list view's banner, providing actions that can be performed on the list or selected records.
The other options are not standard UI Action types:
* A. Workflow action: While workflows can include actions, "Workflow action" is not a defined UI Action type in ServiceNow.
* B. Record navigation button: This is not a standard term used for UI Action types in ServiceNow.

A report is a graphical representation of data from one or more tables in ServiceNow. The following are true for reports in ServiceNow:
Can be a graphical representation of data. This is true because reports can use various chart types, such as pie, bar, line, or gauge, to visualize data in a meaningful way.
Can be run on demand by authorized users. This is true because reports can be accessed from the Reports menu or the Report Navigator and run by users who have the appropriate roles and permissions to view the data.
Can be scheduled to be run and distributed by email. This is true because reports can be configured to run at a specific time and frequency and send the results to one or more email recipients.
The following are not true for reports in ServiceNow:
Any user can see any report shared with them. This is false because users can only see reports that are shared with them if they also have access to the data source of the report. For example, a user who does not have the itil role cannot see a report based on the incident table, even if the report is shared with them.
All users can generate reports on any table. This is false because users can only generate reports on tables that they have access to and that are enabled for reporting. For example, a user who does not have the admin role cannot generate reports on the sys_user table, which is the table for user records. Reference: Reports, Report Security
