Answer : A. Intensive cultivation 

 

Explanation :

 

Intensive cultivation is the main cause of land degradation in Punjab. This refers to the practice of growing crops on the same land year after year without allowing the land to rest and regenerate, which can lead to soil depletion and degradation. Over irrigation, deforestation, and overgrazing can also contribute to land degradation, but they are not the main cause in Punjab.
