Comprehensive and Detailed Step-by-Step Explanation:
* Table Extension in ServiceNow:Extending a table in ServiceNow means creating a child table based on a parent table. The child table inherits the fields, configurations, and functionality of the parent table.
* What is Inherited:
* Fields: All fields from the parent table are available in the child table.
* Functionality: The child table benefits from any business logic or workflows defined for the parent table.
* Access Controls: The child table respects the Access Control rules defined for the parent table unless explicitly overridden.
* Why Other Options Are Incorrect:
* Option B: This is incorrect because the new table does inherit fields from the parent table.
* Option C: This is incorrect because you do not need to script or configure behaviors from scratch; they are inherited.
* Option D: This is incorrect because Access Controls are not ignored; they still apply and can be extended or modified for the child table.
