JDBC-ODBC Connection

Hi,
can anyone know the answer for this question?

Code:

Connection con = DriverManager.getConnection ( 
"jdbc:odbc:wombat", "login", "password"); 
Statement stmt = con.createStatement(); 
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM Table1"); 
while (rs.next()) { 
Integer x = rs.getInt("c"); 
String s = rs.getString("a"); 
Float f = rs.getFloat("b"); 
} 

What is WRONG with the code above?
Choice 1
Retrieval of the fields is in the wrong order.
Choice 2
The password must be encrypted before being sent to the DriverManager.
Choice 3
The Driver's URL is in the wrong format.
Choice 4
The ResultSet class returns primitive types for integers and floats.
Choice 5
The SQL statement is invalid.
