Match the following column and select the correct option.
Column I `" "` Column II
Hardwood `" "` Duramen
Softwood `" "` Alburnum
Heartwood `" "` Non-porous wood
Sapwood `" "` Porous wood

Options

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

Answer

To solve the matching question, we need to pair the terms in Column I with the correct descriptions in Column II. Let's go through each term step by step.

### Step-by-Step Solution:

1. **Hardwood**:
- Hardwood is derived from angiosperms and is characterized by the presence of vessels. This type of wood is also known as porous wood because of these vessels.
- **Match**: Hardwood → Porous wood (Column II: Alburnum)

2. **Softwood**:
- Softwood comes from gymnosperms and lacks vessels, containing only tracheids and parenchyma. Due to the absence of vessels, softwood is referred to as non-porous wood.
- **Match**: Softwood → Non-porous wood (Column II: Duramen)

3. **Heartwood**:
- Heartwood is the central part of the tree, composed of dead cells. It is often referred to as duramen, which is the term for the inner, non-living part of the wood.
- **Match**: Heartwood → Duramen (Column II: Non-porous wood)

4. **Sapwood**:
- Sapwood is the outer, living layer of wood that is responsible for the transport of water and nutrients. It is also known as alburnum.
- **Match**: Sapwood → Alburnum (Column II: Porous wood)

### Final Matches:
- **Hardwood** → Alburnum (Porous wood)
- **Softwood** → Non-porous wood
- **Heartwood** → Duramen
- **Sapwood** → Alburnum

### Correct Option:
The correct option based on the matches is:
- A → Alburnum
- B → Non-porous wood
- C → Duramen
- D → Alburnum
