Internal fertilization occurs in -

Options

A. Many, fungi
B. Reptiles, mammals
C. Bryophytes, pteridophytes, gymnosperms, angiosperms
D. AII

Answer

**Step-by-Step Solution:**

1. **Understanding Internal Fertilization:**
- Internal fertilization is a reproductive process where the male gametes (sperm) fertilize the female gametes (egg) inside the female's body. This is in contrast to external fertilization, where fertilization occurs outside the body.

2. **Identifying Organisms with Internal Fertilization:**
- Internal fertilization is common in various groups of organisms, including:
- **Mammals:** Most mammals, including humans, exhibit internal fertilization.
- **Reptiles:** Many reptiles also reproduce through internal fertilization.
- **Certain Fungi:** Some fungi can also undergo internal fertilization through the transfer of gametes.

3. **Considering Other Groups:**
- The question also mentions groups like bryophytes, pteridophytes, gymnosperms, and angiosperms. While these groups primarily reproduce through external fertilization mechanisms (like pollen transfer), they do not typically exhibit internal fertilization.

4. **Conclusion:**
- Based on the information, the correct answer to the question "Internal fertilization occurs in" would be mammals and reptiles primarily. The inclusion of fungi may also apply in specific cases, but plants (bryophytes, pteridophytes, gymnosperms, and angiosperms) do not typically exhibit internal fertilization.

5. **Final Answer:**
- Internal fertilization occurs in mammals and reptiles, and in some specific fungi.
