The correct answer is Account disablement. This aligns best with the company's policy as it refers to the process of automatically disabling accounts that are inactive for a certain period. This policy helps reduce the risk of unauthorized access from dormant accounts. The other options, while they could also be related to account management, do not specifically address the issue of handling inactive user accounts directly. Password reuse refers to the practice of using the same password across multiple accounts or systems and does not address inactivity. Password complexity ensures passwords are difficult to guess but does not address account inactivity. Network location policies restrict where accounts can log in from but are unrelated to inactivity. Lockout and Password history policies are important for account security but they mainly deal with incorrect authentication attempts and password change management, respectively, and not with inactive accounts.
