Options

A. Reptilia
B. Arthopoda
C. Coelenterata
D. Mammalia .

Answer

To determine which class the whale fish belongs to, let's analyze the options provided:

1. **Reptilia**: This class includes reptiles such as snakes, lizards, and turtles. Members of this class are typically characterized by laying eggs and having scaly skin.

2. **Arthropoda**: This is a diverse group that includes insects, arachnids, and crustaceans. Members of this class have jointed limbs and an exoskeleton. They are also oviparous, meaning they lay eggs.

3. **Coelenterata**: This group includes organisms like jellyfish and corals. They are primarily aquatic and have a simple body structure. They also reproduce through eggs, but their fertilization is internal.

4. **Mammalia**: This class includes mammals, which are characterized by features such as having hair or fur, mammary glands that produce milk for feeding young, and typically giving birth to live young (viviparous).

Now, considering the characteristics of the whale fish:

- The whale fish is a type of mammal, specifically a marine mammal.
- It gives birth to live young rather than laying eggs, which is a defining characteristic of mammals.

Based on this analysis, we can conclude that the whale fish is a member of **Mammalia**.

### Final Answer:
Whale fish is a member of **Mammalia**.
