Question: Which choice best describes what the _resolve_ property does in this route configuration?

1. Prior to loading the _UserComponent_, the router will subscribe to the _Observable_ returned by a _resolve_ method in the _UserResolverService_. This technique can be used to get preloaded data for a _route_.
2. After the _route_ is done resolving, and the component is loaded and rendered, the _UserResolverService_ will have a method named _user_ run that will clean up any open data connections.
3. There is an error. The correct property name is _onResolve_.
4. The _UserComponent_ will have a parameter in its constructor for _user_, and the _router_ will handle injecting in a value for that from a call to a _user_ method in the _UserResolverService_.

Answer: The correct answer of the above question is Option A:Prior to loading the _UserComponent_, the router will subscribe to the _Observable_ returned by a _resolve_ method in the _UserResolverService_. This technique can be used to get preloaded data for a _route_.
