A 'type' is one particular specimen (or a group of specimens) of an organism to which the scientific name of that organism is formally attached. Match colum I (type) with colum II (description) and select the correct option from the codes given below.
`{:(,"Colum I",,"Column II"),(A.,"Holotype",(i),"A specimen cited with original description other than the holotype or isotype"),(B.,"Isotype",(ii),"A duplicate of the holotype"),(C.,"Paratype",(iii),"A specimen designated in the original designated in the original description"),(D.,"Lectotype",(iv),"A specimen selected from original material to serve as nomenclatural type when the holotype was not designated"):}`

Options

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

Answer

To solve the question, we need to match the types of specimens (Column I) with their corresponding descriptions (Column II). Let's go through each type and its description step by step.

### Step-by-Step Solution:

1. **Holotype (A)**:
- **Definition**: A holotype is a single specimen that is designated as the type of a species by the original author at the time the species name and description were published.
- **Matching Description**: This corresponds to (iii) "A specimen designated in the original description."

2. **Isotype (B)**:
- **Definition**: An isotype is a duplicate of the holotype of a species.
- **Matching Description**: This corresponds to (ii) "A duplicate of the holotype."

3. **Paratype (C)**:
- **Definition**: A paratype is a specimen that is not formally designated as a type but is cited along with the type collection in the original description of the taxon.
- **Matching Description**: This corresponds to (i) "A specimen cited with the original description other than the holotype or isotype."

4. **Lectotype (D)**:
- **Definition**: A lectotype is a specimen selected from the original material to serve as the nomenclatural type when the holotype was not designated.
- **Matching Description**: This corresponds to (iv) "A specimen selected from original material to serve as nomenclatural type when the holotype was not designated."

### Final Matching:
- A (Holotype) → (iii) "A specimen designated in the original description."
- B (Isotype) → (ii) "A duplicate of the holotype."
- C (Paratype) → (i) "A specimen cited with original description other than the holotype or isotype."
- D (Lectotype) → (iv) "A specimen selected from original material to serve as nomenclatural type when the holotype was not designated."

### Conclusion:
The correct matching is:
- A → iii
- B → ii
- C → i
- D → iv

Thus, the correct option is **1st option**: A → iii, B → ii, C → i, D → iv.
