B Correct answer
Explanation

The physical layer in OBI EE repository can use any schema structure - normalized, denormalized, or star schema. It's not required to be a star schema; that's a design choice for performance, not a requirement. The Business Model and Mapping (BMM) layer is where dimensional modeling happens.
