Correct Option: B
Explanation:

To answer this question, the user needs to understand what spool space is and its purpose in a database system.

Option A is incorrect because spool space is not a parameter that is specified during the creation of a user; it is a system resource that is managed by the database.

Option B is correct because spool space is used to store intermediate result sets generated during query processing. Intermediate results are stored in spool space before they are written to disk or sent back to the user.

Option C is incorrect because spool space is not permanent space. It is a temporary storage area that is allocated to each user session and released when the session ends.

Option D is incorrect because spool space is not limited to the size of the table. It is a separate resource that is managed independently of the table storage.
