Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of a partitioned tablespace.

A partitioned tablespace is a method used in database management systems to improve the performance and manageability of large tables. It involves dividing a table into smaller, more manageable units called partitions. Each partition is stored in a separate data file within the tablespace.

Now let's evaluate each option:

Option A) True - This option states that individual partitions cannot be independently recovered and reorganized. This is incorrect. In a partitioned tablespace, individual partitions can be independently recovered and reorganized. This is one of the advantages of using partitioning, as it allows for more granular management of data.

Option B) False - This option states that individual partitions can be independently recovered and reorganized. This is the correct answer. In a partitioned tablespace, individual partitions can be independently recovered and reorganized. This allows for more flexibility in managing the data within the table.

The correct answer is B) False. Individual partitions can be independently recovered and reorganized in a partitioned tablespace.
