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.

Risk assessment is the overall process of risk identification, risk analysis, and risk evaluation. Option A describes only one component: risk identification. This is where risks are found, recognized, and described. Option B describes risk analysis, where the organization understands the nature of risk and determines the level of risk, often by considering likelihood and consequence. A full assessment also requires risk evaluation, where the analyzed risk is compared against criteria to determine whether it is acceptable or requires treatment. ISO/IEC 27002 relies on this risk-based logic because controls should be selected according to actual security needs. The standard provides guidance on controls, but it does not require every organization to implement every control in the same way. Risk assessment helps determine which controls are necessary, how strongly they should be implemented, and what residual risk remains. This is why option C is the complete and correct answer. ISO/IEC 27002 control implementation is meaningful only when linked to risk, context, business value, and obligations.
