Correct answer: B
Database views are virtual tables that do not store data physically, unlike materialized views. A key advantage of using views is security; they allow database administrators to restrict access by exposing only specific subsets of data, such as hiding sensitive columns. While views can be queried like regular tables, their update capabilities depend on the underlying query definition.
