Which one of the birds is viviparous

Options

A. Ostrich
B. Penguin
C. Albatross
D. None

Answer

**Step-by-Step Solution:**

1. **Understand the Terms:**
- Define "viviparous": Viviparous animals give birth to live young rather than laying eggs. The embryos develop inside the female's body.
- Define "oviparous": Oviparous animals lay eggs, from which the young hatch.

2. **Analyze the Options:**
- **Ostrich:** This bird lays eggs, making it oviparous.
- **Penguin:** This bird also lays eggs, classifying it as oviparous.
- **Albatross:** Similar to the previous two, albatrosses lay eggs, hence they are oviparous.
- **Nun:** This option is less clear, but if it refers to a type of bird, it is likely also oviparous.

3. **Conclusion:**
- Since all the options provided (ostrich, penguin, albatross, and nun) are oviparous, none of them are viviparous. Therefore, the answer to the question is that none of the listed birds are viviparous.

**Final Answer:**
None of the birds listed (ostrich, penguin, albatross, nun) are viviparous.
