Question

Given below are two statements:

Statement I: Non-biodegradable wastes are generated by thermal power plants.

Statement II: Biodegradable detergents lead to eutrophication.

In the light of the above statements, choose the most appropriate answer from the options given below.

• A. Statement I is false but statement II is true
• B. Statement I is true but statement II is false
• C. Both statement I and statement II are false
• D. Both statement I and statement II are true

Answer 1

The correct option is B Statement I is true but statement II is false

Answer: (b)

Thermal power plants are known to pump out a lot of greenhouse gases and ash, which are by-products of burning the fossil fuels. These are non biodegradable wastes.

Statement II: Biodegradable detergents do not contain phosphate salts as these type of salts lead to over enrichment of phosphate causing water bodies to be choked with algae and other plants (eutrophication). So statement II is false.
