In some types of pine tree,a thick layer of needles protects the buds from which new growth proceeds; consequently they are able to withstand forest fires relatively well.

• A
  
  a thick layer of needles protects the buds from which new growth proceeds; consequently they are able to withstand forest fires relatively well
  
  
  
• B
  
  a thick needle layer protects buds from where new growth proceeds, so that they can withstand forest fires relatively well
  
  
  
• C
  
  a thick layer of needles protect the buds from which new growth proceeds; thus, they are able to withstand relatively well any forest fires
  
  
  
• D
  
  since the buds from which new growth proceeds are protected by a thick needle layer, consequently they can therefore withstand forest fires relatively well
  
  
  
• E
  
  because the buds where new growth happens are protected by a thick layer of needles, they are able to withstand forest fires relatively easily as a result
