Step 1: Understanding the Concept:
This question tests knowledge of the storage life of different citrus fruits.
Step 2: Detailed Explanation:
Citrus fruits have varying storage lives depending on their peel thickness, acidity, and sugar content.
Grapefruits have the longest storage life among citrus fruits, lasting 8-12 weeks at optimum temperature (10-15°C).
Their thick peel and high acidity make them less susceptible to decay.
Other citrus storage lives:
- Nagpur mandarin: 4-6 weeks
- Kinnow mandarin: 6-8 weeks
- Sweet oranges: 6-8 weeks
- Grapefruits: 8-12 weeks
Factors affecting storage life:
- Peel thickness (thicker = longer storage)
- Acidity level (higher = longer storage)
- Variety characteristics
- Storage conditions (temperature, humidity)
Step 3: Final Answer:
Thus, grapefruits have the highest storage life, which corresponds to option (D).
