The data on a failed disk group is being rebuilt on other disk groups. Negative performance impact to VMs is being reported. What can be used to reduce the negative performance impact on the VMs?
A sure.

A is the correct answer.
The vSAN Resynchronization throttling feature reduces the number of IOPS used to perform resynchronization on disk groups in the vSAN cluster. Resynchronization throttling is a cluster-wide setting and it is applied on a per-disk group basis.

C- When a drive fails, many small components fail, such as stripes or mirrors of objects. But new copies of these components are spread around the cluster for balancing. These copies are created as part of the resynchronization and rebalance operations that are initiated by the failures. These operations can cause resource contention, depending on the size of the affected data, but vSAN balances the load for fair distribution.
Proactive rebalancing is related to the fullness of the disks. On the question that is not mentioned but resync is as a disk has failed
