I’m leaning towards B) Private too, but I wonder if there are any exceptions or specific use cases that could change that.

I’m a bit confused. I thought hybrid blockchains could also be limited to one organization, but maybe that’s not the case?

I recall a practice question that mentioned consortium blockchains are shared among multiple organizations, so that rules out C) for this one.

I think the answer might be B) Private, but I'm not completely sure. I remember something about private blockchains being restricted to one organization.
