1. **Identify Primitive Mammals**: The question asks about the most primitive mammals. The two main groups of primitive mammals are monotremes and marsupials.

2. **Understanding Monotremes**: Monotremes are a group of egg-laying mammals. They are considered the most primitive of all mammals. There are only five species of monotremes, with the platypus being the most well-known.

3. **Understanding Marsupials**: Marsupials are another group of primitive mammals that give birth to underdeveloped young, which then continue to develop in a pouch on the mother's body. Examples include kangaroos and koalas.

4. **Geographical Distribution**: Both monotremes and marsupials are primarily found in Australia and Tasmania. This is important because it helps to narrow down the options provided in the question.

5. **Evaluate the Options**:
- Africa: Incorrect, as primitive mammals are not primarily found here.
- Asia: Incorrect, as this region does not host the majority of primitive mammals.
- Australia and Tasmania: Correct, as these regions are home to both monotremes and marsupials.
- America: Incorrect, as primitive mammals are not native to this continent.

6. **Conclusion**: Based on the information gathered, the correct answer to the question is that the most primitive mammals are found in Australia and Tasmania.

**Final Answer**: Australia and Tasmania.
