ACow dung

BKitchen waste

CDDT

DPaper

Answer:

C. DDT

Read Explanation:

  • Correct Answer: Option C - DDT

  • Non-biodegradable pollutants are substances that cannot be broken down by natural processes or microorganisms in the environment. These pollutants persist in the ecosystem for a very long time and can cause long-term environmental damage.

  • Cow dung - This is organic waste that can be easily decomposed by microorganisms. It is completely biodegradable and is even used as manure in agriculture.

  • Kitchen waste - This mainly consists of food scraps and organic materials that decompose naturally. It is biodegradable and can be composted.

  • DDT (Dichlorodiphenyltrichloroethane) - This is a synthetic chemical pesticide that persists in the environment for decades. It is highly resistant to environmental degradation and is a classic example of a non-biodegradable pollutant. DDT accumulates in the food chain and can cause serious ecological problems.

  • Paper - While paper takes longer to decompose than food waste, it is still biodegradable. Under proper conditions, paper can break down within 2-6 weeks.
