Question

Assertion: Recycling is the best solution for the treatment of e-wastes
Reason: E-wastes are often buried in landfills or incinerated

• A. Both assertion and reason are true and reason is the correct explanation for the assertion
• B. Both assertion and reason are true but the reason is not the correct explanation for the assertion
• C. Assertion is true but reason is false
• D. Both assertion and reason are false

Answer 1

The correct option is B Both assertion and reason are true but the reason is not the correct explanation for the assertion

E-wastes refer to ‘electronic wastes’ and include discarded electronic items such as batteries, mobile phones, computers, etc. They are hazardous wastes as they contain toxic chemicals and heavy metals (cadmium, mercury, etc.) which can harm human health and also pollute the soil. These wastes are often buried in sanitary landfills or incinerated but the best way to get rid of e-wastes is to recycle it in an eco-friendly way.
E-wastes generated by developed nations are often exported to developing nations such as India, China, etc. where metals such as gold, nickel, silicon, copper, etc. are extracted from the wastes and are recycled.
Hence, both assertion and reason are true but the reason does not correctly explain the assertion.
