The typical deployment of a servlet involves which of the following:
a) The servlet's class file is placed in one of the directories in the CLASSPATH of the Servlet Engine

b) The servlet is serialized and placed in the root directory of the Servlet Engine.

c) The servlet must be registered with the Servlet Engine before it can be found by a URL used in a web browser.

d) The Servlet Engine must be stopped and then restarted before the new servlet can be loaded.

Any ideas on what is the best answer?

Well, (a) is wrong because the Only Right Place[TM] for servlet class files (and application object code in general) is WEB-INF/classes or a jar in WEB-INF/lib. (b) is wrong because servlets aren't usually serialized, and you certainly don't need a serialized servlet to deploy. You do need to use the WEB-INF/web.xml file declare a servlet and map it to one or more virtual paths on the server, which counts as "register" I guess, making (c) correct. (d) may be true for some application servers, but others will re-load the configuration file and deploy the servlet without restart so it is false in general.
Which makes (c) the only plausible answer.
