In Node.js, objects that emit events are instances of the EventEmitter class. The standard way to subscribe to an event is by using the .on() method. The first argument is the name of the event, and the second is a callback function to execute when the event is emitted. For handling errors in an event-driven architecture, the conventional event name is 'error'. This code correctly attaches a listener to the error event on the server object.

A. server.catch(...) is the syntax for handling promise rejections, not for listening to events from an EventEmitter.

B. server.error(...) is not a standard method on the EventEmitter class for listening to error events.

D. try...catch blocks are used for handling synchronous exceptions, not for handling asynchronously emitted 'error' events.
