The command 'docker-compose down' is specifically designed to stop and remove the containers, networks, volumes, and images that are defined in your Docker Compose file. When you run this command, it effectively cleans up the whole environment that was set up by the docker-compose up command. This includes stopping any running services and removing them from the Docker environment, ensuring that there are no lingering containers or associated resources left after the command is executed.

This functionality is vital for managing the lifecycle of your application deployed via Docker Compose, as it allows for a quick and efficient teardown of the entire stack. The volume and images removal can also help reclaim system resources and help in scenarios where re-deploying or redeploying with changes is intended.

In contrast, the other options represent functionalities that do not align with what 'docker-compose down' accomplishes. Creating new resources falls under the responsibility of commands like 'docker-compose up' or 'docker-compose create'. Updating containers with new images would generally require a different set of commands like 'docker-compose pull' and 'docker-compose up --force-recreate'. Lastly, displaying logs is the domain of 'docker-compose logs' or 'docker logs', and is not connected to the operation of stopping and removing resources.
