Answer:
c. Cow dung
Explanation:
Cow dung is biodegradable. It is also a natural fertilizer. It contains organic matter that helps the soil become rich in nourishment.
Aluminum cans take upto 500 years to decompose
Polythene bags don't break down naturally, they undergo photo decomposition which breaks into microplastics and harm the air.
DDT is a fat soluble chemical which becomes more harmful as it moves up the food chain
