C Correct answer
Explanation

The correct way to connect to a MySQL database in PHP uses the mysql_connect() function. Option A's dbopen() doesn't exist, option B's mysql_open() is not a standard PHP function, and option D's connect_mysql() is also not a valid function.

AI explanation

In the classic PHP MySQL extension (mysql_*), the function used to open a connection to a MySQL server is mysql_connect("hostname"). Functions like dbopen, mysql_open, or connect_mysql don't exist in PHP's MySQL API, so mysql_connect is the only valid syntax among the choices.
