The notion of mounting directories in Docker is essential for data persistence and sharing between the host and containers. When it comes to specifying the destination for a mounted directory, it is important to understand how Docker interprets paths.

The correct answer indicates that the destination must be a relative path. However, this is not accurate because the destination can be specified as an absolute path within the container's filesystem. Using an absolute path for the destination allows for more precise control over where the data is being mounted within the container.

For example, if you mount a host directory to /data within a container, you would use an absolute path to specify the location correctly, ensuring that the mounted contents are accessible at that specific location regardless of the current working directory in the container.

This flexibility of specifying destination paths leads to clearer management of volumes and makes it easier to structure data storage inside the container. The other options align with Docker's mounting functionality. You can indeed use -v or --mount for mounting, the source must be an absolute path from the host, and, while you can mount files as well as directories, it’s important to note that Docker allows both types of mounts.
