Answer: D

Explanation:

The best way to prevent accepting bad data from a third-party service provider is to implement business rules to reject invalid data. Business rules are logical expressions that define the business requirements and constraints for specific data elements. They can be used to validate, transform, or filter incoming data from external sources, ensuring that only high-quality data is accepted into the enterprise data warehouse. Business rules can also help to identify and resolve data quality issues, such as missing values, duplicates, outliers, or inconsistencies.
