Which solution will require the least amount of administrative work and the least amount of service interrupti

A vSphere 5 implementation consists of a fully automated DRS cluster with two ESXi 5.x hosts with the following vNetwork Standard Switch configuration:

1. Switch A: two vmnics, one port group named sFTP-PG

2. Switch B: one vmnic, one port group named Web-PG

3. All vmnics are trunked to the same physical switch.

DRS has been configured with an anti-affinity rule for all virtual machines in the Web-PG so that no more than half of the virtual machines run on any given host. The virtual machines on WebPG are experiencing significant network latency. The network team has determined that a performance bottleneck is occurring at the ESXi host level.

Which solution will require the least amount of administrative work and the least amount of service interruption?

A.
Move a vmnic from Switch A to Switch B on each host

B.
Migrate Web-PG to Switch A and sFTP-PG to Switch B on each host

C.
Convert the three Switch Bs to a single vNetwork Distributed Switch

D.
Use vMotion to redistribute some of the VMs in Web-PG to a different ESXi host
