`{:(,"Column I",, "Column II"),(A.,"Ecology",(i),"Relationships of organisms and environment"),(B.,"Herbarium",(ii),"Original specimen cited by an auther"),(C.,"Holotype",(iii),"A hierarchial unit"),(D.,"Taxon",(iv),"Collection of wild and domestic plants"):}`

Options

A. A-(i), B-(ii), C-(iii), D-(iv)
B. A-(i), B-(ii), C-(iv), D-(iii)
C. A-(i), B-(iv), C-(ii), D-(iii)
D. A-(iv),B-(ii), C-(iii), D-(i)

Explanation

To solve the matching question, we will analyze each item in Column I and find the corresponding item in Column II based on their definitions.

### Step-by-Step Solution:

1. **Identify the first item in Column I: Ecology (A)**
- Definition: Ecology is the study of relationships between living organisms and their physical environment.
- Match: This corresponds to (i) "Relationships of organisms and environment".
- **Pairing**: A - (i)

2. **Identify the second item in Column I: Herbarium (B)**
- Definition: A herbarium is a collection of preserved plant specimens, which can include both wild and domestic plants.
- Match: This corresponds to (iv) "Collection of wild and domestic plants".
- **Pairing**: B - (iv)

3. **Identify the third item in Column I: Holotype (C)**
- Definition: A holotype is a single specimen designated by the original describer of a species or subspecies, serving as the original specimen cited by an author.
- Match: This corresponds to (ii) "Original specimen cited by an author".
- **Pairing**: C - (ii)

4. **Identify the fourth item in Column I: Taxon (D)**
- Definition: A taxon is a group of one or more populations of organisms that are classified together, often seen as a hierarchical unit.
- Match: This corresponds to (iii) "A hierarchical unit".
- **Pairing**: D - (iii)

### Final Pairings:
- A - (i)
- B - (iv)
- C - (ii)
- D - (iii)

### Summary of the Correct Pairing:
- A (Ecology) → (i) Relationships of organisms and environment
- B (Herbarium) → (iv) Collection of wild and domestic plants
- C (Holotype) → (ii) Original specimen cited by an author
- D (Taxon) → (iii) A hierarchical unit

### Correct Option Code:
The correct pairing can be summarized as:
- A1, B4, C2, D3
