`{:(,"Column I ",,"Column II"),((a),"Commerical rubber",(i),"Manihot"),((b),"Chicle gum",(ii),"Carica"),((c),"Papain",(iii),"Achras"),((d),"Opium",(iv),"Papaver"):}`

Options

A. `a-(i), b-(ii), c-(iii), d-(iv)`
B. `a-(i), b-(iv), c-(ii), d-(iii)`
C. `a-(i), b-(ii), c-(iii), d-(iv)`
D. `a-(iii), b-(i), c-(ii), d-(iv)`

Answer

To match the plant products with their respective plants, we need to identify the source of each product listed in Column I and find the corresponding plant name in Column II.

### Step-by-Step Solution:

1. **Identify Commercial Rubber:**
- Commercial rubber is obtained from the rubber tree, scientifically known as *Hevea brasiliensis*.
- It does not match any of the options in Column II directly, but let's keep it noted for further comparison.

2. **Identify Chicle Gum:**
- Chicle gum is derived from the sap of the sapodilla tree, which is scientifically known as *Manihot*.
- Therefore, Chicle gum corresponds to (i) *Manihot*.

3. **Identify Papain:**
- Papain is an enzyme obtained from the papaya plant, scientifically known as *Carica papaya*.
- Thus, Papain corresponds to (ii) *Carica*.

4. **Identify Opium:**
- Opium is obtained from the poppy plant, scientifically known as *Papaver somniferum*.
- Hence, Opium corresponds to (iv) *Papaver*.

### Final Matching:
- (a) Commercial rubber - (iii) Achras (This is incorrect as it should be *Hevea brasiliensis*)
- (b) Chicle gum - (i) Manihot
- (c) Papain - (ii) Carica
- (d) Opium - (iv) Papaver

### Summary of Matches:
- **Commercial rubber**: *Hevea brasiliensis* (not listed in Column II)
- **Chicle gum**: *Manihot* (i)
- **Papain**: *Carica* (ii)
- **Opium**: *Papaver* (iv)
