Final answer:
If owner p deletes all of the owner q's rights to an object in a system that allows multiple owners, q would be unable to access the object until their rights are reinstated, under the system's governance on property rights and ownership.
Step-by-step explanation:
In a system that allows multiple owners of an object, where owners can grant and delete rights, if owner p deletes all of owner q's rights to the object, then q would no longer have access to the object under their ownership rights. This action, however, presumes it's allowed within the system's rules to remove another owner's rights entirely. The property rights framework of such a system typically establishes that an owner cannot take away another owner's ownership status but can modify the access rights. Therefore, even if p deletes q's rights, it may not affect q's underlying ownership of the object but would effectively prevent them from accessing it until those rights were reinstated, subject to the system's governance policies and rules regarding tenure and ownership.
