Fruits stored in a cold chamber exhibit longer storage life because
View correct answer and explanation
Correct answer: C
Correct Option: C
Explanation: Cool storage slows respiration, ripening enzymes and microbial spoilage in harvested fruits, prolonging their shelf life.
Option-wise Analysis:
A: Incorrect - Not the main reason: avoiding direct sun helps, but refrigeration works chiefly by reducing metabolic activity.
B: Incorrect - Not generally decisive: carbon-dioxide enrichment requires controlled-atmosphere storage, not simply a cold chamber.
C: Correct - Correct: lower temperature decreases cellular respiration and ripening rate.
D: Incorrect - Not the chief mechanism: relative humidity can limit shrivelling but does not explain the central temperature effect.
