The correct answer is option 2) i.e. DCAB.

  • D is the first sentence because it introduces the classification of water pollution, which is discussed further.
  • C tells us that marine pollution and nutrient pollution are subsets of water pollution. 'Subset' means 'a part of a larger group', so C comes after D.
  • A mentions sources of water pollution and B further explains it, so, B comes after A. AB is a pair.
