Final answer:
The true statement about vSAN three-node cluster configuration is that you can apply a deduplication and compression rule to a virtual machine object. It cannot tolerate two host failures nor can a RAID-5/6 erasure coding be applied to it.
Step-by-step explanation:
The correct statement about vSAN three-node cluster configuration is that a storage policy with a deduplication and compression rule can be applied to a virtual machine object.
Three-node clusters do not have the capability to tolerate two host failures, irrespective of the number of disk groups in each host. The failure tolerance for three-node configurations is limited to a single host failure.
Additionally, a storage policy with RAID-5/6 erasure coding cannot be applied to a three-node vSAN setup because RAID-5/6 erasure coding necessitates a minimum of four nodes.
