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.
