in frog oviduct is formed by

Options

A. Wolffian duct
B. Bidder's canal
C. Matenepheric
D. Mullerian duct

Answer

To answer the question "In frog, oviduct is formed by," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Oviduct**: The oviduct is a crucial part of the female reproductive system in frogs. It plays a significant role in the transport of eggs from the ovaries to the outside of the body.

2. **Identifying the Structures**: In the context of frog anatomy, we have several ducts that are associated with the reproductive system. The options given are:
- Wolfian duct
- Bedder's canal
- Metamorphic
- Mullerian duct

3. **Recognizing the Correct Duct**: Among the options, the Mullerian duct is known to be associated with the formation of the female reproductive system. It is specifically responsible for forming the oviducts in female frogs.

4. **Understanding the Formation**: The Mullerian ducts are paired embryological structures that undergo fusion during development. This fusion is essential for the proper formation of the oviducts.

5. **Conclusion**: Therefore, the correct answer to the question is that the oviduct in frogs is formed by the Mullerian duct.

### Final Answer:
The oviduct in frogs is formed by the **Mullerian duct**.
