Final answer:
The term describing when a child folder has the same permissions as its parent folder is 'Inheritance'. This happens in file systems, allowing permissions to propagate from parent to child objects, ensuring consistent access control.
Step-by-step explanation:
When a child folder has the same permissions as its parent folder, this is referred to as permission inheritance. In file systems that support permissions, such as NTFS on Windows, inheritance is a feature that allows child objects, like files and subfolders, to automatically receive the access permissions of their parent folder.
The correct answer to the question is D. Inheritance. This is a fundamental concept in access control for file systems, where often, for convenience and to avoid repetitive configuration, a child folder will inherit the permissions set on a parent folder unless explicitly set otherwise.
