Overriding inheritance allows you to apply specific policies to individual OUs without affecting the policies of the parent OU or other sibling OUs. This gives you granular control over different groups of users or devices.
Other options are incorrect because:
* A: Deleting sub-level OUs would remove the management structure and negate the purpose of having OUs.
* B: Disabling auto-updates would prevent devices from receiving important security and feature updates.
* D: Forcing inheritance would apply the top-level OU policy to all sub-OUs, preventing customization.
