To determine the appropriate temperature range for a refrigerator, you need to consider the optimal conditions that keep food safe and fresh.
Step-by-Step Solution:
1. Understanding Temperature Ranges:
- Option (A): 28°F to 30°F.
- Option (B): 38°F to 40°F.
- Option (C): 48°F to 50°F.
- Option (D): 0°F.
2. Assessing Each Range:
- Option (A): 28°F to 30°F: This temperature range is too low for standard refrigerator settings. It is close to freezing, which would cause many food items to freeze, thus not ideal for typical refrigeration.
- Option (C): 48°F to 50°F: This range is too high for safe refrigerator storage. At these temperatures, food would spoil quickly because these temperatures are in the danger zone for bacterial growth.
- Option (D): 0°F: This is the standard temperature for freezers, not refrigerators. A temperature of 0°F will freeze food solid, which isn't the goal for a refrigerator.
3. Determining the Correct Temperature Range:
- Option (B): 38°F to 40°F: This range is ideal for keeping food fresh and safe for consumption in a refrigerator. It is cold enough to slow down bacterial growth but not too cold to freeze the food.
So after evaluating all the options, the correct temperature range for a refrigerator is:
(B) 38°F to 40°F.
Therefore, the answer is: 2.
