5C is your answer. Standard virtual switches (vSwitches) live on each ESXi host because they are host-local constructs that handle the layer-2 switching for VMs running on that specific host, with no dependency on vCenter, NSX Manager, or the VMs themselves.
C is your girl, every single time. Picture each ESXi host wearing its own little network hat, because standard vSwitches live right there on the host itself, not up in vCenter-land or anywhere else, which is exactly why you need to configure them separately on each host rather than from one central spot.
Standard vSwitch config is definitely per-host, but the reason that actually bites you is drift, where host 2 gets a typo in the MTU or a missing uplink and you only find out when a desktop pool starts throwing protocol errors at logon time.
C is right. A standard vSwitch lives on the ESXi host itself, not on vCenter, so every host you add to your environment needs its own vSwitch configured independently, which is exactly why vDS was introduced later to centralize that management.
Took the 1V0-604 last spring and this one came up almost word for word, and I almost second-guessed myself thinking vCenter had something to do with it until I remembered that standard vSwitches live right on the ESXi host itself, no vCenter required. Spun up a nested ESXi lab the week before and physically watched the vSwitch get created per host, so when I saw option C I clicked it without hesitation.
