Answer: (A)

Usurpation in the context of information systems refers to the scenario where an unauthorized entity takes control of system services or resources. This act threatens the integrity and security of the information system, as the individual or entity that has usurped control can manipulate, corrupt, or exploit the system for malicious purposes. This can lead to various security breaches, including data theft, service disruption, or unauthorized data alteration.

Understanding usurpation is crucial for developing effective security measures. It highlights the importance of ensuring that only authorized users have access to system services, thereby preventing unauthorized access and potential damage to the system's integrity.
