Correct, Physical controls are anything you physically can touch. An iris scanner falls under the bio metric access control which scans for your physical characteristics.
Physical controls are defined as any controls that you can physically touch. So, this is a tricky one because an iris scanner is a physical device, that you can touch and it can stand in your way of entry..
I think the answer may be A – LOGICAL.
Logical is another term for Technical which is over the firewall and “authentication”
Iris Scanning is an authentication item.
Physical i believe only applies to physical barriers like locked doors, bollards, fences, etc.
