Options

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

Answer

To solve the problem of matching Column I with Column II, we need to identify the correct associations between the terms in both columns. Let's go through each item step by step.

### Step-by-Step Solution:

1. **Identify Protochordata**:
- In Column I, we have "A. Protochordata".
- In Column II, we need to find the organism that belongs to this group. The correct match is "Doliolum" (iv), which is a type of protochordate.
- **Match**: A → iv

2. **Identify Limbless Amphibia**:
- Next, we look at "B. Limbless Amphibia".
- The organism that fits this description is "Ichthyophis" (v), which is a genus of caecilians, commonly known as limbless amphibians.
- **Match**: B → v

3. **Identify Oviparous Mammal**:
- Now, we check "C. Oviparous Mammal".
- The organism that lays eggs among mammals is "Ornithorhynchus" (iii), which is the scientific name for the platypus.
- **Match**: C → iii

4. **Identify Aquatic Mammal**:
- Moving on to "D. Aquatic Mammal".
- The organism that is an aquatic mammal is "Delphinus" (i), which refers to dolphins.
- **Match**: D → i

5. **Identify Jawless Vertebrate**:
- Finally, we look at "E. Jawless Vertebrate".
- The correct match here is "Myxine" (ii), which is commonly known as hagfish and is a jawless vertebrate.
- **Match**: E → ii

### Summary of Matches:
- A → iv (Doliolum)
- B → v (Ichthyophis)
- C → iii (Ornithorhynchus)
- D → i (Delphinus)
- E → ii (Myxine)

### Final Answer:
The correct option based on the matches is the second one.
