Answer: (C)

Verified step by step guidance

1. Understand the purpose of measuring temperature in food safety: to ensure the entire product has reached a safe temperature, not just the surface or surrounding air.
2. Recognize that the temperature in the air above the smoothie or on the surface may not accurately represent the temperature inside the smoothie, where bacteria could survive if not properly cooled.
3. Identify that the most accurate temperature reading comes from the center of the smoothie, as this is the last part to reach the desired temperature during cooling or heating.
4. Know that placing the thermometer probe against the side of the container can give misleading readings because the container may be cooler or warmer than the smoothie itself.
5. Therefore, to ensure food safety, always insert the thermometer probe into the center of the smoothie to get an accurate measurement of its internal temperature.
