Answer: (A)

Physical security focuses on protecting people and equipment through tangible controls. It covers measures like locks, guards, access-control systems, barriers, and surveillance to prevent unauthorized entry to facilities and devices. The description—physical measures designed to safeguard personnel and prevent unauthorized access to equipment—directly matches this domain. Information security concentrates on protecting data and information systems from cyber threats, not on physical barriers. Personnel security deals with ensuring trusted individuals through background checks and related policies, rather than physical access controls. Cybersecurity targets the protection of networks, software, and digital assets from cyber attacks.
