To determine the correct temperature range for food storage, let's analyze the given options:
a) 5-10 degrees Celsius in the refrigerator and -24 to -26 degrees Celsius in the freezer
- The recommended temperature range for a refrigerator is 0-5 degrees Celsius to keep food fresh and prevent bacterial growth.
- The recommended freezer temperature is between -18 to -25 degrees Celsius to maintain frozen food quality and safety.
- This option suggests 5-10 degrees Celsius for the refrigerator and -24 to -26 degrees Celsius for the freezer. The refrigerator range is too high, making this option incorrect.
b) 0-5 degrees Celsius in the refrigerator and -18 to -25 degrees Celsius in the freezer
- This option perfectly aligns with the recommended temperature ranges for both the refrigerator and the freezer.
- The range for the refrigerator (0-5 degrees Celsius) is correct for keeping food fresh.
- The range for the freezer (-18 to -25 degrees Celsius) is correct for maintaining food quality and safety in frozen conditions.
- This option is therefore correct.
c) 18 to 25 degrees Celsius in the refrigerator and 0 to 5 degrees in the freezer
- The suggested refrigerator range (18-25 degrees Celsius) is too high, making it unsuitable for food storage as bacteria can grow, leading to food spoilage.
- The freezer range (0-5 degrees Celsius) is incorrect because it won't keep food frozen and safe.
- This option is incorrect.
d) -2 to -8 degrees Celsius in the refrigerator and -12 to -20 degrees Celsius in the freezer
- The suggested refrigerator range (-2 to -8 degrees Celsius) is too cold and falls outside the recommended range, potentially freezing items that shouldn't be frozen.
- The freezer range (-12 to -20 degrees Celsius) is not as effective as the recommended range and might not maintain food safety as well.
- This option is incorrect.
Based on the analysis:
The correct answer is b) 0-5 degrees Celsius in the refrigerator and -18 to -25 degrees Celsius in the freezer.
