Detailed answer by Teachoo

• The type of soil erosion that is caused by running water is called gully erosion . 
• Clue i and clue iii are the most useful clues in identifying gully erosion because they describe the distinctive features of this type of soil erosion. 
• Clue i describes how gully erosion cuts through the clayey soils and makes deep channels , which is a characteristic effect of running water on the land surface. 
• Clue iii describes how gully erosion makes the land unfit for cultivation and is known as bad land , which is a consequence of soil loss and degradation. 
• These two clues are specific to gully erosion and differentiate it from other types of soil erosion. 
  Thus , the correct answer is option (B): clue i and clue iii
