Assertion:
Evencs refers to a scientific method of treating e-wastes in an environment friendly manner.
Reason:
Recycling of e-wastes in developed countries often involves manual participation and exposes the workers to toxic substances present in e-wastes.

A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C. Assertion is correct but the Reason is incorrect
D. Both Assertion and Reason are incorrect

Hint: Discarded electrical or electronic devices are known as electronic waste or e-waste. Used electronics that are set up for reuse, resale, and recycling through material recovery, or disposal are also considered as e-waste. Processing of e-waste in developing countries in an unmethodical way can lead to adverse human health effects and environmental pollution.

Complete answer: E-waste is the waste that comes from electrical or electronic equipment which refers to all components, sub-assemblies, and consumables, which are part of the product at the time of discarding. E-waste is primarily defined as any substance or object that the holder disposes of or is required to dispose of under the provisions of the national law in force.
The main problem with the management of e-waste is its cumulative number of quantiles. This e-waste produces a small quantity of the overall solid waste. There are a huge number of e-waste generated every year both in a developed and developing country.
Normally e-waste elements are too expensive. They are also potentially toxic elements and formation of e-waste depends on several factors like the type of electronic device, date of manufacturing, and the using period of the device. A large amount of a scrap of e-waste comes from the IT and telecommunication sector which contain a higher amount of expensive materials in comparison to the household e-waste.
Disposal of e-waste is a very critical system. Most developed countries take initiative and build law for the purpose of proper treatment and disposal as well as recycling of e-waste. Disposal of e-waste is mainly done by landfilling like the other waste or burning openly which releases toxic substances to nature. In developing countries, the disposal of e-waste is so informal and undeveloped.
Evencs is a method of e-waste management that is done by proper scientific guidelines and through an eco-friendly way. Generally, more than half of the total amount of e-waste is exported by the developed country to the developing country and there are recycled and reused. As we say that the developed countries have proper laws, their manual participation is not allowed to recycle e-waste as it leads to their intoxication. Recycling of e-wastes in developing countries often executes by manual participation and leads the workers to the effect of toxic substances that are present in e-wastes. Therefore, the assertion is correct but the reason is incorrect.

Hence, the correct answer to the question is option C.

Note: Discarded electronic devices are known as e-waste. The amount of this type of waste is increasing day by day due to the electronic boom. To dispose and recycle this waste, the proper scientific system is required. Evencs is such a method. The developed countries follow the proper guideline in e-waste management, but in developing countries still manual practice is followed which leads to harmful implications in the persons directly involved in their disposals.
