Correct Option: A
Explanation:

The given statement is:

SELECT TO_CHAR(TRUNC(SYSDATE),'MM/DD/YYYY HH24:MI:SS') FROM dual;

Let's break down the statement:

  1. TRUNC(SYSDATE): This truncates the current date and time to the nearest day, setting the time component to 00:00:00.

  2. TO_CHAR(TRUNC(SYSDATE),'MM/DD/YYYY HH24:MI:SS'): This converts the truncated date and time to a string format with the specified format mask.

Considering the given date and time is 09/09/2009 09:09:09, when we truncate this date and time, the time component will be set to 00:00:00, resulting in 09/09/2009 00:00:00.

Therefore, the statement will return "09/09/2009 00:00:00".

The correct answer is A) 09/09/2009 00:00:00.
