b.Creates an instance of the servlet class.
c.Initializes the servlet instance by calling the init method

Answer / nishidh soni

Servlet is initialized by two ways...

1)By initializing the constructor:-but in the initial version of JDK 1.0 constructor can not be initialized for the dynamic page loading so that init() method for the servlet comes into the picture.

2)By invoking the init() method:-This init() method is invoked by the servlet container at it is invoked once per servlet and it uses the ServletConfig as a object for the initialized parameter.and the it is like
init(ServletConfig config)
{
.....
}
