  1. Fixed
  2. Fixed AP
  3. Round Robin
  4. Most recently used
Explanation
Answer: C - Round Robin path selection policy allows for I/O to be spread across multiple paths to active-active storage arrays. An example of this would be using multiple VMkernel ports to connect ISCSI-based storage with multiple controllers in an active-active configuration. This will spread the I/O load across multiple paths to multiple controllers, thereby greatly increasing throughput and decreasing latency.
