   I think it’s C and D

   Storage I/O Control enables storage traffic shaping and priority within a vSphere environment. This is feature similar to Network I/O Control (NIOC) and compute resource pools. A congestion threshold can be enabled to guarantee storage traffic priority. A latency threshold can be configured to ensure a datastore is always achieving below a configured millisecond response time. If the datastore goes above that number, vSphere attempts to limit the I/O from all hosts to that particular datastore in an effort to lessen the latency. This setting can also be set to a dynamic percent threshold to better calculate the appropriate millisecond response type dependent on the type of storage used.

   SDRS also provides affinity/anti-affinity rules for VMDKs; this means you can specify disk files that should reside together or apart. In general, it is best to leave them together unless you have a specific reason to separate them.
   Once enabled, many features are available to be configured for how to automate your storage environment. Those options are as follows:
   Free space threshold
   Latency threshold
   VM affinity/anti-affinity rules
