C. It retains the indexes defined on the table. This is true. The TRUNCATE TABLE operation does not drop the indexes on the table; it only removes all rows from the table.
D. It retains the integrity constraints defined on the table. This is correct. The TRUNCATE TABLE operation does not affect the integrity constraints; it retains them.
Options A, B, E, and F are incorrect:
A is incorrect because the TRUNCATE TABLE operation cannot be rolled back as it is a DDL operation and not a DML operation like DELETE.
B is incorrect because TRUNCATE TABLE does not drop any triggers; they remain in place.
E is incorrect as TRUNCATE TABLE may or may not release the space depending on whether the REUSE STORAGE clause is used.
F is incorrect because FLASHBACK TABLE cannot be used to retrieve data after a TRUNCATE TABLE operation since it does not generate redo logs that FLASHBACK relies upon.
