What is the maximum amount of time perishable foods can safely be left at room temperature (between 40°F and 140°F / 4°C and 60°C) before they become unsafe to eat due to rapid bacterial growth?

✓ Correct Answer: Option C

The 'danger zone' for bacterial growth in food is between 40°F (4°C) and 140°F (60°C). Perishable foods should not be left in this temperature range for more than two hours, or one hour if the ambient temperature is above 90°F (32°C).
