You need to select the appropriate model type for the Finance database. Which model type should you select?

Star schema is a relational database design pattern involving fact and dimension tables - it describes a physical schema layout, not an SSAS model type, and cannot be selected as a model in SSAS.

The SSAS Multidimensional model stores data in OLAP cubes using the MOLAP, ROLAP, or HOLAP storage modes and is queried via MDX, providing rich support for complex financial calculations, key performance indicators, and hierarchical analysis. It has been the traditional enterprise OLAP platform with mature support for writeback, many-to-many relationships, and advanced cube scripting. For a Finance database requiring sophisticated aggregations and business logic, Multidimensional is the appropriate SSAS model type.

Relational is a general database paradigm, not an SSAS model type, and selecting a relational approach would bypass the OLAP capabilities needed for multidimensional financial analysis.

Tabular with PowerPivot uses the VertiPaq in-memory columnar engine and DAX for queries, which is simpler to develop but lacks some of the advanced financial modeling features - such as complex MDX calculations and writeback - available in the Multidimensional model.
