Which of the following statement is INCORRECT related to mysql_list_tables() function ?

Why this is correct: mysql_list_tables() (from the old PHP mysql_* extension) requires an active DB connection (link identifier) to query the server for table list. So saying a connection is not needed is incorrect. Why the others are correct: 1.      The function is intended to list tables in a database. 2.      You must establish a connection first (true). 3.      The result resource can be used with mysql_tablename() to extract table names (true). Note: the mysql_* PHP extension is deprecated and removed in newer PHP versions in favor of mysqli /PDO, but the behavior above is the historical behavior relevant to the question.
