I feel like I might be mixing things up, but option A doesn't seem right. I don't recall seeing `--share-with` in the Docker documentation.

I practiced a similar question, and I believe the correct command is C. It makes sense to use `--volumes-from` to access the existing volume.

I'm not entirely sure, but I remember something about using `-v` to specify volumes. Could it be option B?

I think we need to use the `--volumes-from` option to share the volume from the datastore container. So maybe it's option C?

Ah, I see now. Option C is the way to go - using the --volumes-from flag to share the volume.

Because the --volumes-from flag is used to share volumes between containers.

I think the correct answer is C. The --volumes-from option allows you to share a volume between containers.
