1. The problem asks for the four enhancing qualitative characteristics according to the IASB's Conceptual Framework for Financial Reporting. 2. The Conceptual Framework defines enhancing qualitative characteristics as those that improve the usefulness of information provided in financial reports. 3. The four enhancing qualitative characteristics are: comparability, verifiability, timeliness, and understandability. 4. Let's analyze the options: - Option 1 includes consistency and faithful representation, which are fundamental qualitative characteristics, not enhancing. - Option 2 lists concepts like accrual basis and going concern, which are accounting principles, not enhancing characteristics. - Option 3 mixes faithful representation and relevance, which are fundamental characteristics, not enhancing. - Option 4 correctly lists comparability, timeliness, understandability, and verifiability, matching the IASB framework. 5. Therefore, the correct answer is option 4: comparability, timeliness, understandability, verifiability.
