Question

all of the following are safe ways to thaw frozen food except:
placing the frozen food under drinkable running water at 70°f or lower.
cooking the frozen food as part of a regular cooking procedure.
carefully covering the frozen food then place in a sanitized container at room temperature.
placing the frozen food in a refrigerator at 41°f or lower.

Explanation:

Safe food thawing methods keep food out of the "danger zone" (40°F to 140°F) where bacteria grow rapidly. Refrigerating, using cold running water, and cooking directly are all safe. Thawing at room temperature lets food stay in the danger zone, allowing bacterial growth, so it is unsafe.

Answer:

carefully covering the frozen food then place in a sanitized container at room temperature.
