Instance variables are variables for which each instantiated object of the class has a separate copy, or instance. In the context of an httpd (HTTP Daemon) class, port, cache, and log can all be instance variables. The port would be used to specify the listening port for HTTP requests, the cache could be used to store cached data to improve performance, and the log could be an instance variable used to log requests, errors, or other information. Therefore, all of the mentioned options are plausible instance variables for an httpd class.
