Final answer:
A steak should not be located on the front rail of the grill waiting to be placed on a plate due to the risk of contamination and the steak entering the temperature danger zone.
Step-by-step explanation:
The place a steak should NOT be located is b. On the front rail of the grill waiting to be placed on a plate.
Proper food handling and safety protocols dictate that raw or cooked food should not be left out in the open, such as on a rail, where it has a higher risk of contamination or entering the temperature danger zone where bacteria can grow. Instead, a steak should be stored in a steak tray in the meat cooler when not being cooked, on the grill cooking when it's being prepared, or on a plate ready to serve when it's ready to be eaten.
