A Correct answer
Explanation

Oracle's DATE data type stores century information along with year, month, day, hours, minutes, and seconds. The DATE type uses 7 bytes internally and includes full date precision including century.

AI explanation

Oracle's internal DATE datatype is stored as a fixed 7-byte binary format encoding century, year, month, day, hour, minute, and second (each byte typically representing one of these components, offset-adjusted). This is why Oracle DATE always carries time-of-day precision to the second and full century/year information internally, regardless of the display format (NLS_DATE_FORMAT) used when querying. So the statement that century information is recorded is True — it's a core piece of Oracle DBA/developer knowledge about the internal representation of DATE columns.
