Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the glans penis of rodents and bats, specifically what it possesses. The glans penis is the rounded tip of the penis, which is significant in the reproductive anatomy of these animals.

2. **Identifying the Options**: The options provided are:
- Ospenis
- Oscordus
- Both 1 and 2
- None of the above

3. **Explaining Ospenis**: Ospenis, also known as the penile bone or baculum, is a bone found in the penis of many placental mammals, including rodents and bats. It aids in copulation and varies in size and shape among different species.

4. **Explaining Oscordus**: Oscordus is a structure unrelated to the penis; it is a bone located near the heart in cows. Therefore, it is not relevant to the question about the glans penis.

5. **Evaluating the Options**:
- Since the glans penis of rodents and bats possesses the ospenis, this option is correct.
- The option for oscordus is incorrect as it does not relate to the penis.
- Therefore, options "Both 1 and 2" and "None of the above" are also incorrect.

6. **Conclusion**: The correct answer is **Ospenis**.
