Hi,

As the GenericServlet have a abstract service() method, It should be override by the extending Servlet.

The option C is correct. The Code will compile without this method call, but the ServletConfig object will not available. The Specification mandate when overriding this form of method, call super.init(config). Looking reasonable.

Thanks
