THE CORRECT OPTION IS SHIFTING CULTIVATION,because shifting cultivation is the process whereby a farmer used a particular area of land and later determined to abadon the land for some years,the purpose is mainly to enrich the soil with adequate minerals and nutrient....choosing LEY FARMING is WRONG,choosing MIX FARMING also is WRONG,and choosing CROP ROTATION is also WRONG,so the correct option is SHIFTING CULTIVATION.
