Ans. Option b) is correct: Both of these
Deforestation is caused by human activities as well as by natural causes. 

Causes of deforestation by human activities:
  • Due to increase in the needs agriculture is expanding, for which they are clearing the forests.
  • They are clearing the forests for using these land as a grazing land.
  • They are clearing the forests for timber collection.
  • Fire is also a major cause of deforestation.
  •  They are clearing forests for building dams.
  • Mining is also a cause, for digging mines they first need to clear the land by removing forests.
  • Palm oil is also a major cause of deforestation, demand of palm oil is increasisg day by day which leads to increase in deforestation.
  • Cultivation shifting is also a cause of deforestation, farmers shift their land for cultivation when their land becomes unfertile.

Following are the natural causes of deforestation:
  • Forest fire
  • Drought
  • Flood
  • Climate change
  • Overpopulation of wildlife 

P.S. In one of the options, you have written 'Natural resources'. However, it should be 'Natural causes'. I have revised the question and sent you the solution accordingly.
