Which command is used to list all Docker volumes?

The command used to list all Docker volumes is "docker volume ls." This command provides a straightforward way to see all volumes created in the Docker environment, allowing users to manage and utilize these storage resources effectively.

Docker volumes are essential for persistent data storage, particularly when containers are stopped or removed. By using the "docker volume ls" command, you can quickly access a list of all the defined volumes along with their names and other relevant information. The syntax of this command directly follows Docker’s command structure, emphasizing its role in the Docker CLI for volume management.

The other options do not correspond to valid Docker commands for listing volumes. They either use incorrect syntax or do not conform to the command structure expected in Docker environments. Thus, "docker volume ls" is the correct and efficient way to list all volumes in Docker.
