C Correct answer
Explanation

A data warehouse is organized around major subject areas (customers, products, sales) rather than business applications or functions. This subject-oriented design is a core characteristic. Option A is wrong (end users don't update warehouses), B is wrong (warehouses standardize naming), and D is wrong (warehouses contain historical data).
