TCS foods, or foods that require time and temperature control for safety, should be kept at either 41°F or lower or 135°F or higher. This is because these temperatures prevent bacteria from growing to unsafe levels in food. Room temperature (option A) is not safe for TCS foods as it falls within the temperature danger zone (41°F-135°F). Freezing (option B) does not apply to the temperature range for TCS foods and can actually cause texture and quality changes in some foods. Exactly 100°F (option D) is also not within the recommended temperature range for TCS foods and can promote bacterial growth. So, the best option for storing TCS foods is to keep them at either 41°F or lower or 135°F or higher.
