Explanation:

Biological Oxygen Demand is the amount of dissolved oxygen that is required by the bacteria to oxidise biodegradable material present in water. Greater BOD value implies higher amount of pollution in water and hence lower value of Dissolved Oxygen. Since BOD covers only biodegradable materials it is slightly less significant indicator of pollution. Chemical Oxygen Demand considers amount of dissolved oxygen for oxidation of non-biodegradable substance as well. Hence, statement 2 is incorrect and therefore, answer is B.
