To retrieve data using native SQL from the SAP HANA database, you should...

The correct approach includes specifying the database schema if it is not the user's default schema. In SAP HANA, each database user has a default schema, and if a table resides in a different schema, the query must explicitly reference that schema. This ensures clarity and precision in the SQL statement, allowing the database engine to correctly locate the desired tables. Omitting the schema when accessing tables outside of the default can lead to confusion or errors in the query execution.

While using the UP TO n ROWS addition, a comma-separated column list, or an ORDER BY clause can be useful in specific contexts, they are not universally required or relevant for all data retrieval scenarios in native SQL. The necessity of mentioning the schema is foundational in ensuring that a SQL command is directed to the correct data source, which reinforces why option B is the most accurate choice for retrieving data in this context.
