• A. p-i, q-ii, r-iv, s-iii
• B. p-iv, q-iii, r-ii, s-i
• C. p-iii, q-iv, r-i, s-ii
• D. p-iv, q-iii, r-i, s-ii

Answer 1

Answer: (B)

p-iv, q-iii, r-ii, s-i

• (p)e-waste - (iv)Irreparable waste - Irreparable computers and other electronic goods are known as electronic wastes (e-waste). Electronic waste or e-waste describes discarded electrical or electronic devices. When electronic waste is thrown away in landfills their toxic materials seep into groundwater, affecting both land and sea animals.
• (q)Biodegradable waste - (iii)Green waste -Green waste is an organic waste that can be composted. As green waste can be degraded by natural processes into some usable forms they are called a biodegradable waste.
• (r)Inert waste - (ii)Dirt -Inert waste is waste which is neither chemically nor biologically reactive and will not decompose. Examples of this are sand and concrete. Inert waste is also called as dirt.
• (s)Composite waste -(i)Waste clothing - Composite is a material made of 2 or more materials. Hence the overall properties are dependent on the type of reinforcement and matrix. Once the material has done its part and it no longer used it is needed to be replaced.
• So, the correct answer is 'p-iv, q-iii, r-ii, s-i'
