Which two View Dimension Members are used for entering commentary? Select two.

The choice regarding which View Dimension Members are utilized for entering commentary prominently focuses on the purpose and functionality of each member. The option 'C. Annotation' is specifically designed for capturing qualitative feedback or commentary related to financial data or reports. Annotations serve as notes or explanations that provide additional context for the figures presented, enhancing the understanding of the data.

In the context of financial reporting, annotations are critical for users to communicate insights, justifications, or any relevant information that helps stakeholders interpret the numbers correctly. This functionality directly aligns with the need for a dedicated member that allows for commentary entry, distinguishing it from other options that do not fulfill this purpose.

The other choices, such as Year-to-Date (YTD) and RestofYear, represent specific time periods for financial reporting rather than serving as mechanisms for commentary. These terms typically refer to the aggregation of values over a specified timeframe and do not provide a space for qualitative insights. The term 'Variance' relates to the difference between expected and actual figures but similarly lacks the specific capability to accommodate commentary.
