    While answer D correlates with the vSphere 5 documentation, I have a hard time conceiving how that would work. What they’re saying in the third bullet seems to be:

    If you create a VM in vSphere 5 as a Hardware Version 8 VM, then you attach a disk that was created using an earlier version of vSphere, using for example Hardware Version 7, the new VM will revert back to Hardware Version 7.

    I find that hard to believe.
