Correct answer
BBoth statement I and statement II are true.
Step-by-step explanation
Non-biodegradable wastes are generated by thermal power which produce fly ash.
Nowadays most of the detergents available are biodegradable. The bacteria responsible for degrading biodegradable detergent feed on it and grow rapidly. While growing, they may use up all the oxygen dissolved in water which cause Eutrophication.
