Question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). 

Assertion (A) : Adopting ecofriendly methods and bio degradable substances for dying and printing processes in textile and garment making can save the resources of the nature and reduce chemical land fill in a big way. 

Reason (R) : Bio-degradable dyes donot require heavy metals, amines and inorganic salts. Hence they do not easily get decomposed without leaving any landfill in the environment. 

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

The correct answer is
(A) is correct but (R) is not correct

Assertion (A): Eco-Friendly Textile Processes

Statement (A) claims that using eco-friendly methods and biodegradable substances in textile dying and printing conserves natural resources and significantly reduces chemical landfill waste. This is accurate. Sustainable textile practices are designed specifically to minimize environmental impact by reducing pollution and resource depletion.

Reason (R): Biodegradable Dyes Characteristics

Statement (R) asserts that biodegradable dyes do not require heavy metals, amines, or inorganic salts. It then concludes, "Hence they do not easily get decomposed without leaving any landfill in the environment." The first part of this reason is generally true – many eco-friendly dyes avoid such harmful components. However, the conclusion contradicts the definition of biodegradable. Biodegradable substances are meant to decompose easily and naturally, thus *minimizing* landfill issues, not creating them. Therefore, the reasoning provided is flawed and inaccurate regarding the decomposition and landfill impact.

Conclusion

Based on the analysis, Assertion (A) is correct as it accurately describes the benefits of sustainable textile practices. Reason (R) contains an incorrect conclusion about the decomposition and landfill effects of biodegradable dyes.

Therefore, the most appropriate answer is that (A) is correct but (R) is not correct.
