Answer

### Step-by-Step Solution:

1. **Understanding Taxonomy**: Taxonomy is the science of classification of living organisms. It involves organizing and categorizing organisms based on their characteristics.

2. **Components of Taxonomy**: Taxonomy includes three main components:
- **Identification**: Recognizing and naming organisms based on their features.
- **Nomenclature**: Assigning a scientific name to organisms that is universally accepted.
- **Classification**: Grouping organisms into hierarchical categories such as kingdom, phylum, class, order, family, genus, and species.

3. **Evaluating the Options**:
- **Option A**: Connection of plants and animals - This is incorrect as taxonomy encompasses all organisms, not just the relationship between plants and animals.
- **Option B**: Classification of organisms - This is a part of taxonomy but does not encompass its entirety.
- **Option C**: Identification, nomenclature, and classification of organisms - This accurately describes the complete scope of taxonomy.
- **Option D**: All of the above - This is incorrect since not all previous options are correct.

4. **Conclusion**: The correct answer is **Option C**: Identification, nomenclature, and classification of organisms, as it fully encompasses the definition and scope of taxonomy.
