Lower CPU consumption is, imho, related to the virtual machine itself.

P.C.S.O.R.says:
In the link you provide it says clearly “SplitRX adds CPU overhead, so it can actually hurt performance in other scenarios.” Reason it goes against the question.
The correct answer is A.
” Multiple virtual machines on one ESXi host all receiving multicast traffic from the same source.
(SplitRx mode will typically improve throughput and CPU efficiency for these workloads.)”
Should be B.

Its B. Look at the official guide from vmware.
