Correct Answer: Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Solution : The correct answer is (a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
Electronic waste, or e-waste, consists of discarded electronic devices such as computers, smartphones, and appliances. These devices often contain hazardous substances, including heavy metals like lead, mercury, and cadmium, as well as harmful chemicals like brominated flame retardants. If not managed properly, these substances can leach into the environment and pose risks to human health and ecosystems. The reason correctly explains why e-waste management is crucial for sustainable development. Proper e-waste management involves various practices, including recycling, refurbishment, and responsible disposal. By recycling and properly managing e-waste, hazardous substances can be safely recovered or disposed of, minimizing the environmental and health risks associated with their improper handling.
Sustainable development aims to achieve a balance between economic growth, social well-being, and environmental protection. E-waste management is an essential component of sustainable development because it addresses both environmental and health concerns associated with the improper handling of electronic waste.
Therefore, both the assertion and the reason are correct, and the reason provides the correct explanation for the assertion.
