Option C is incorrect because data marts are subsets of data warehouses, and users in a data warehouse access data from the warehouse itself. Option D is incorrect because data analysts who work with a data warehouse are typically knowledgeable about data analysis and data modeling, rather than being experts in a particular business function.
