Answer: D

Red soil is formed as a result of weathering of metamorphic and igneous rocks. The red color of the soil comes from the high percentage of iron content.  

  • The soil’s texture varies from being sandy to clayey, but it is mainly loamy. Red soil is rich in potash content but lacks phosphate, humus and nitrogen content.  
  • The red soil is found in regions such as Tamil Nadu, Madhya Pradesh, Jharkhand, Odisha, some parts of Karnataka and southeast Maharashtra.
