Continual improvement is the process of increasing an organization’s effectiveness and efficiency so that it better fulfills its policies and objectives. In information security, improvement is not limited to fixing one defect. It is the ongoing refinement of controls, processes, responsibilities, technologies, awareness, monitoring, and response capabilities. Option B describes analysis, which may support improvement but is not the definition. Option C describes correction or corrective action for a nonconformity, which can be one mechanism of improvement but does not cover the complete concept. ISO/IEC 27002 supports continual improvement through controls such as learning from information security incidents, independent review, compliance monitoring, threat intelligence, vulnerability management, change management, and documented operating procedures. A mature organization uses evidence from incidents, audits, metrics, user behavior, supplier performance, new threats, and business changes to adjust its controls. The key idea is progressive enhancement of suitability, adequacy, and effectiveness. Therefore, option A aligns with the management system and ISO/IEC 27002 control logic.

==========

ISO/IEC 27002 requires equipment to be sited and protected in a way that reduces risks from physical and environmental threats. These threats include fire, flood, dust, vibration, electrical interference, unauthorized access, power instability, temperature extremes, and other environmental hazards. Option A is correct because secure siting and protection of equipment are essential to preserving confidentiality, integrity, and availability of information processing facilities. Option B is incorrect because equipment can absolutely be affected by power failures, utility disruptions, voltage fluctuations, overheating, and related events. Option C is incorrect because supporting utilities should be maintained, monitored, and tested as appropriate over time, not only at the beginning. ISO/IEC 27002 physical controls emphasize that technical systems depend on the physical environment. Servers, network devices, storage, and endpoint systems need appropriate location, power, cooling, cabling protection, and resilience measures. Equipment placement should also reduce unauthorized viewing, tampering, theft, and environmental exposure. The verified answer is option A because it reflects the physical protection objective in ISO/IEC 27002.
