Suggested answer: C

Explanation:

The best environment for copying data and transforming it into a compatible data warehouse format is the staging environment. The staging environment is a temporary area where data from various sources are extracted, transformed, and loaded (ETL) before being moved to the data warehouse. The staging environment allows for data cleansing, validation, integration, and standardization without affecting the source or target systems. The testing environment is not suitable for copying data and transforming it into a compatible data warehouse format, as it is used for verifying and validating the functionality and performance of applications or systems. The replication environment is not suitable for copying data and transforming it into a compatible data warehouse format, as it is used for creating identical copies of data or systems for backup or recovery purposes. The development environment is not suitable for copying data and transforming it into a compatible data warehouse format, as it is used for creating or modifying applications or systems.Reference:
