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

To solve the matching question, we need to match the items from Column 1 with the correct items from Column 2 based on their definitions and characteristics. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify E-waste
- **Definition**: E-waste refers to discarded electrical and electronic equipment that is no longer wanted or usable, and cannot be repaired.
- **Match**: E-waste corresponds to **Irreparable waste**.
- **Conclusion**: P (e-waste) matches with (iv) Irreparable waste.

### Step 2: Identify Biodegradable Waste
- **Definition**: Biodegradable waste can be broken down naturally by microorganisms and returns to the soil. It includes organic matter that can be composted.
- **Match**: Biodegradable waste corresponds to **Green waste**.
- **Conclusion**: Q (biodegradable waste) matches with (iii) Green waste.

### Step 3: Identify Inert Waste
- **Definition**: Inert waste is waste that is neither chemically nor biologically reactive and does not decompose easily. Examples include sand and concrete.
- **Match**: Inert waste corresponds to **Dirt**.
- **Conclusion**: R (inert waste) matches with (ii) Dirt.

### Step 4: Identify Composite Waste
- **Definition**: Composite waste is a heterogeneous mixture of different types of materials, including textiles and plastics.
- **Match**: Composite waste corresponds to **Waste clothing**.
- **Conclusion**: S (composite waste) matches with (i) Waste clothing.

### Final Matching:
- P (e-waste) → (iv) Irreparable waste
- Q (biodegradable waste) → (iii) Green waste
- R (inert waste) → (ii) Dirt
- S (composite waste) → (i) Waste clothing

### Summary of Matches:
- P → (iv)
- Q → (iii)
- R → (ii)
- S → (i)
