Which is viviparous

Options

A. Bony Fish
B. Shark
C. Lung Fish
D. Frog

Answer

To determine which organism is viviparous among the given options, we will analyze each option based on their reproductive methods.

### Step-by-Step Solution:

1. **Understanding Viviparous**:
- Viviparous organisms give birth to live young ones rather than laying eggs. This means that the young develop inside the parent's body.

2. **Analyzing the Options**:
- **Bony Fish**:
- Bony fish are primarily oviparous, meaning they lay eggs. The eggs are fertilized outside the body, and the young hatch from these eggs. Therefore, bony fish cannot be considered viviparous.

- **Shark**:
- Sharks are known to exhibit a form of viviparity. They produce eggs that develop inside the female's body. The eggs hatch within the uterus, and the young sharks are born live. Thus, sharks are viviparous.

- **Lungfish**:
- Lungfish are also oviparous. They lay eggs in water, and the young develop from these eggs. Hence, lungfish do not qualify as viviparous.

- **Frog**:
- Frogs are oviparous as well. They lay eggs in water, which hatch into tadpoles, and later develop into adult frogs. Therefore, frogs are not viviparous.

3. **Conclusion**:
- After analyzing all the options, the only organism that is viviparous is the **Shark**.

### Final Answer:
- The correct answer is **Shark**.
