Options

A. cow
B. mouse
C. pig
D. all

Answer

**Step-by-Step Solution:**

1. **Understanding Transgenic Animals**: Transgenic animals are those that have had a foreign DNA sequence deliberately inserted into their genome. This process is done to study gene function, produce proteins, or improve agricultural traits.

2. **Examples of Transgenic Animals**:
- **Cow**: There are transgenic cows that have been engineered to produce milk with enhanced nutritional properties or to be resistant to certain diseases.
- **Mouse**: Mice are commonly used as model organisms in research and can be genetically modified to study various diseases and biological processes.
- **Pig**: Transgenic pigs have been developed for various purposes, including organ transplantation and enhanced growth rates.

3. **Identifying the Correct Answer**: Since all the mentioned animals (cow, mouse, pig) are examples of transgenic animals, the correct answer to the question is "all of the above."

4. **Final Answer**: Therefore, the answer is option four: all the above.
