Option C is the correct answer because it addresses the need for proper access control and data security in a Databricks environment by implementing role-based access control (RBAC) through dynamic views. This approach ensures that users only have access to the data they are authorized to see, which is crucial for compliance and security. Additionally, RBAC is scalable and can be cost-effectively managed, making it the best practice for data governance in this scenario. Options A, B, and D either neglect the importance of access control or fail to provide a balanced solution that considers both security and scalability.
