Solution

The correct option is C Assertion is correct but Reason is incorrect
Leaving the field uncultivated for one or more seasons is called fallowing. Fallowing was employed in old times for improving the soil fertility. The practice is, however, not possible these days because of the limited land and large population. Growing of alternate crops in the similar successive seasons on the same piece of land is called crop rotation. Multiple cropping is raising of two or more crops in succession in a single year on the same piece of land. So, the correct answer is 'Assertion is correct but Reason is incorrect'.
