Aqualitative risk analysismethod uses nonnumerical categories such as low, medium, and high to describe the consequences and probability of risks. This method involves subjective judgment based on expertise, experience, and intuition rather than mathematical calculations. Qualitative methods are often used when it is challenging to obtain accurate numerical data, and they provide a general understanding of risks to prioritize them for further action. Option C is correct because the use of nonnumerical categories aligns with the qualitative risk analysis methodology. Option A (Quantitative) is incorrect as it involves numerical values and statistical methods, while Option B (Semi-quantitative) is a mix of qualitative and quantitative methods, usually involving ranges of numerical values.

According to ISO/IEC 27000, information security is defined as the "preservation of confidentiality, integrity, and availability of information." This definition highlights the three core principles of information security:

Confidentialityensures that information is not disclosed to unauthorized individuals or systems.

Integrityensures the accuracy and completeness of information and its processing methods.

Availabilityensures that authorized users have access to information and associated assets when required.

This definition encompasses the protection of information in all forms and aligns with ISO/IEC 27005’s guidelines on managing information security risks. Therefore, option A is the correct answer. Options B and C are incorrect as they refer to more specific aspects or other areas of information management.

Opportunities, according to ISO standards such as ISO 31000, are situations or conditions that have the potential to provide a favorable impact on achieving objectives. They representcircumstances that, when leveraged, can lead to beneficial outcomes for the organization, such as competitive advantage, growth, or improved performance. Option B is correct as it accurately describes opportunities as circumstances expected to be favorable to achieving objectives. Option A (Occurrence or change of a particular set of circumstances) is a more general definition that could apply to both risks and opportunities, while Option C (Outcome of an event affecting objectives) is more aligned with the concept of risk.
