- **Transgenic Plants**: These are plants that have been genetically altered to express desired traits, such as pest resistance or improved nutritional content.
- **Transgenic Animals**: These are animals whose genetic makeup has been modified, often for research purposes or to enhance certain traits.

3. **Evaluating the Options**:
- **Option A**: Transgenic microbes - This is a type of GMO.
- **Option B**: Transgenic plants - This is also a type of GMO.
- **Option C**: Transgenic animals - This is yet another type of GMO.
