What dimensions are available for selection in the driver basis?

The correct answer highlights that all dimensions in the application are available for selection in the driver basis. In the context of Profitability and Cost Management Cloud (PCMCS), the driver basis is a critical element where users can define the factors that influence cost and profitability calculations.

By allowing all dimensions to be selected, PCMCS offers a comprehensive approach for users to analyze various aspects of their financial data. This includes dimensions such as business units, products, customers, and time periods, which can be vital for detailed and nuanced profitability analysis. The flexibility of including all dimensions enables organizations to tailor their analysis precisely to their needs, facilitating deeper insights and better decision-making.

In contrast, other options suggest limitations that would not provide the same level of analytical capability. For instance, excluding certain dimensions or allowing only specific types of dimensions (like business dimensions) would restrict the breadth of analysis that could be performed, potentially missing out on key influences on profitability and costs.
