A is the correct answer. Breaking up the disk groups has the following advantages: • Redundancy: In example one, a single disk groups can result in a host failure. • Flexibility: Scale up or scale out are both viable options. • Performance: More cache devices means more I/O paths. Taken from vSAN 6.7 Deploy and Manage Lecture Manual - Design: One or Multiple Disk Groups Per Host Section

In all flash mode, there is no read cache and directly read to capacity disks. So, Adding or Spliting cache don't improve read performance. I choose B.

Adding multiple disk groups = more IO paths = more performance. A is correct.
