What is the required temperature range for refrigeration?

The required temperature range for refrigeration is typically between 32°F and 41°F. This range is crucial for maintaining the safety and quality of perishable food items. At these temperatures, the growth of bacteria is significantly slowed down, which helps to preserve food and prevent spoilage.

When items are kept below 32°F, they may freeze, which can compromise texture and flavor in some food products. Conversely, temperatures above 41°F can allow bacteria to multiply more rapidly, posing food safety risks. Thus, the 32°F to 41°F range serves as the optimal balance to keep food safe for consumption while maintaining its quality.

While the other choices might seem close, they either fall below the acceptable range (like 28-36°F) or extend into temperatures that are less safe for food preservation, which is why they are not suitable responses.
