Solution :
[d] Khâdir or Khadar and Bângar are terms used in Hindi, Urdu, Punjabi and Sindhi in the Indo-Gangetic plains of North India and Pakistan to differentiate between two types of river plains and alluvial soils. Khadir or Khadar plains are those that are low-lying next to a river. Khadar areas are prone to flooding and sometimes include portions of former river-beds that became available for agriculture when a river changed course. It is moisture retentive and sticky when wet. Khadir soil consists of new alluvial deposits and is often very fertile. Bangar plains are more upland, and consist of older alluvial soil. Bangar areas are less prone to flooding but are usually sandier and less fertile as well.
