Answer: D

Answer to Question 2

A tablespace is a named logical storage unit in which data from one or more tables, views, and indexes can be stored. A tablespace is mapped to one or more physical files in the OS and can be set to increase in size automatically. A tablespace can, in many ways, be thought of as its own file system available to the RDBMS.
