What actions will most likely correct the issue without significantly impacting other users?

Users are experiencing performance issue when updating their database hosted on a virtual machine. The administrator determines that I/O is high across all HBAs on the ESXi host containing the virtual machine.
What actions will most likely correct the issue without significantly impacting other users?

A.
Manually configure the disk multipathing policies to fix for each datastore.

B.
Migrate the virtual machine to a less used datastore with storage vMotion.

C.
Use vMotion to migrate the Virtual machine to another ESXi host.

D.
Map additional LUNs to the ESXi host and extend the datastores.

    I agree with the TJ because vMotion will just change the Host (with out changing the datastore) So VM will bear the same latency on the different Host but same Datastore .

    C is correct. The question states “The administrator determines that I/O is high across all HBAs on the ESXi host containing the virtual machine”, so the problem is on the ESXi, not on the storage. Hence migrating to another host (with more resources on the HBAs) will solve the problem.
    B will NOT solve the problem for the same reason: aonther datastore BUT the HBA on the ESXi are full.
