To answer this question, you need to understand the differences between the commands DROP, DELETE, and TRUNCATE in the context of deleting data from a table.
Option A) DROP - This option is incorrect because the DROP command is used to delete an entire table or database object, including its structure. It does not specifically delete data from a table without affecting the rollback segment.
Option B) DELETE - This option is incorrect because the DELETE command is used to delete specific rows from a table based on a condition. It does write to the rollback segment to allow for a rollback operation if needed.
Option C) TRUNCATE - This option is correct because the TRUNCATE command is used to delete all data from a table, but it does not write to the rollback segment. TRUNCATE is a DDL (Data Definition Language) command that is faster than DELETE because it deallocates the data pages and resets the highwater mark, freeing the space for reuse.
Option D) REMOVE - This option is incorrect because the REMOVE command is not a valid command in most database systems.
Option E) NONE OF THE ABOVE - This option is incorrect because option C (TRUNCATE) is the correct answer.
The correct answer is C) TRUNCATE. This option is correct because it deletes all data from a table without writing to the rollback segment.
