Question

Domestic waste contains
A) Non-biodegradable pollutants
B) Biodegradable pollutants
C) Hydrocarbons
D) Both A and B

Answer 1

Hint: Domestic waste is a non-putrescible waste. Domestic waste is the waste that is collected during household activities like cooking, cleaning, etc. Degradable pollutants degrade after some time.

Step by step explanation:
Option A) Non-biodegradable pollutants: Non-biodegradable pollutants are the substance that cannot be broken down by natural pigments and acts as a source of pollution. Most of the inorganic waste is non-degradable. Non-biodegradable pollutants are not Eco-friendly, they need to be replaced in order to reduce pollution. The threat caused by them is more critical. An example of this is plastics waste.
Option B) Biodegradable pollutants: Biodegradable things can be defined as materials that can be decomposed by bacteria. Biodegradable pollutants are degradable by natural elements. Microorganisms and other abiotic factors work together and break down the substances into simpler organic matters which eventually suspend and dissolve into the soil. They are not added to the pollution. Some examples of such waste are food waste, kitchen waste, and other natural wastes.
Option C) Hydrocarbons: Hydrocarbon is the organic chemical compound composed of hydrogen and carbon atoms.
Option D) both A and B: Domestic waste contains both Non-biodegradable pollutants and Biodegradable pollutants. There are a lot of waste materials that can be classified as degradable and non-degradable waste materials. So proper categorization and proper disposal are needed.

Hence the correct answer is option D.

Note:
We can see a lot of waste that is degradable as well as non-degradable. Domestic waste contains both Non-biodegradable pollutants and Biodegradable pollutants. Non-biodegradable pollutants are the waste that cannot be broken down by natural pigments and acts as a source of pollution. Biodegradable pollutants are those that are broken down by the action of microorganisms and other abiotic factors that work together and break down the substances into simpler organic matter.
