Answer 1

The correct option is C (i), (iv),(ii) and (iii)

Nitrogenous fertilizers used for higher yield in agriculture. Rainfall causes the excess chemicals to mix with water and fertilizers reach the waterbodies. The excess nitrogen in waterbodies aids in the growth of unwanted algae and aquatic plants which creates an unbalance in the environment.
Thus, the correct order of statements will be (i), (iv),(ii) and (iii)
