Options :

A : Regular views do not cache data, and therefore cannot improve performance by cach-ing.

B : As with non-materialized views, a materialized view automatically inherits the privileges of its base table.

C : Cached Query Results: Used only if data has not changed and if query only uses de-terministic functions (e.g. not CURRENT_DATE).

D : Materialized views are faster than tables because of their “cache” (i.e. the query results for the view); in addition, if data has changed, they can use their “cache” for data that hasn’t changed and use the base table for any data that has changed.

E : Both materialized views and regular views enhance data security by allowing data to be exposed or hidden at the row level or column level.
