B is correct as in this situation best to scale up and not out...here is more The combination of disk groups and the efficiency of its integration right into the hypervisor allows vSAN to give you the power of choice in how to best accommodate your technical requirements. Scale out by adding nodes when you need storage and compute. Or scale up by adding disks and disk groups when you need storage capacity and associated performance. https://blogs.vmware.com/virtualblocks/2016/09/15/options-scalability-virtual-san/
