C
Prior to JDBC 4.0, the way to load the Driver was to use the forName method of the Class class. In the parameter, specify the name of the Driver (category path). The program will automatically call the DriverDriver’s registerDriver method to load (register) the Driver.
Option A, which is the mechanism of JDBC 4.0, will be automatically loaded by writing the name of the Driver to the file “META-INF/services/java.sql.Driver”.
Option B, there is no such usage.
Option C, the correct way to load Driver.
Option D, the getDriver method of the DriverManager class is just used to retrieve the loaded Driver object.
