Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : During sun drying of seeds in open air, the seeds are covered with thick tarpaulin or will be transferred back to.

Reason (R) : A decrease in air temperature leads to an increase in relative humidity.
In light of the above statements, choose the most appropriate answer from the options given below

- Assertion (A) is Correct: During traditional open-air sun drying of agricultural seeds on drying floors, the seed lots must be covered with thick tarpaulins or transferred back inside the seed godown before evening sunset.
- Reason (R) is Correct: As ambient air temperature drops during late afternoon and evening, the saturation vapour pressure of air decreases, causing a corresponding sharp increase in relative humidity ($RH$). Because seeds are hygroscopic porous materials, they rapidly absorb moisture from humid night air, reversing the drying process and increasing vulnerability to mold.
- Relationship: The evening drop in temperature causes relative humidity to rise, which triggers hygroscopic moisture re-absorption by dry seeds; therefore, covering or storing seeds before dusk prevents moisture regain, making Reason (R) the direct scientific explanation of Assertion (A).
- Conclusion: Both (A) and (R) are correct and (R) is the correct explanation of (A) (Option 1).
