Which of the following is correct w.r.t. classification of Myxine?

Options

A. Chordata, Agnatha, Pisces, Cyclostomata
B. Chordata, Vertebrata, Agnatha, Cyclostomata
C. Chordata, Vertebrata, Gnathostomata, Chondrichthyes
D. Chordata, Vertebrata, Gnathostomata, tetrapoda

Answer

To determine the correct classification of Myxine, we need to analyze the options provided and understand the taxonomic hierarchy of Myxine (commonly known as hagfish).

### Step-by-Step Solution:

1. **Identify the Taxonomic Hierarchy**:
- Myxine belongs to the phylum **Chordata**. This is the first level of classification.

2. **Determine the Subphylum**:
- Within Chordata, Myxine is classified under the subphylum **Vertebrata**. However, it is important to note that Myxine is a jawless fish, which places it in a specific group.

3. **Classify into Appropriate Class**:
- Myxine is part of the class **Agnatha**, which includes jawless fishes.

4. **Identify the Superclass**:
- Myxine is also classified under the superclass **Cyclostomata**, which comprises jawless fish including both hagfish and lampreys.

5. **Review the Options**:
- Now, let's analyze the options provided:
- **Option 1**: CoData, Agnatha, Pisces, Cyclostomata
- **Option 2**: CoData, Vertebrata, Agnatha, Cyclostomata
- **Option 3**: CoData, Vertebrata, Gnathostomata, Chondrichthyes
- **Option 4**: CoData, Vertebrata, Gnathostomata, Teleostomi

- From our classification, we can see that Myxine is correctly classified as:
- Phylum: Chordata
- Subphylum: Vertebrata
- Class: Agnatha
- Superclass: Cyclostomata

6. **Select the Correct Option**:
- Based on the above classification, **Option 2** (CoData, Vertebrata, Agnatha, Cyclostomata) is the correct classification for Myxine.

### Final Answer:
**The correct classification of Myxine is given in Option 2: CoData, Vertebrata, Agnatha, Cyclostomata.**
