D. Species

Answer

To answer the question "In which of the following, organisms are very much similar to each other," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification Hierarchy**:
- Biological classification is organized in a hierarchical structure that includes several levels: Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each level groups organisms based on shared characteristics.

2. **Identify the Highest Level**:
- The highest level is the Kingdom, which includes a broad range of organisms. For example, the Kingdom Animalia includes all animals, while the Kingdom Plantae includes all plants.

3. **Move Down the Hierarchy**:
- As we move down from Kingdom to Phylum, Class, Order, Family, and Genus, the organisms become more similar. Each lower level groups organisms that share more specific traits.

4. **Focus on the Lowest Level - Species**:
- The lowest level of classification is Species. Organisms within the same species are very much similar to each other. They can interbreed and produce fertile offspring, which is a key characteristic of a species.

5. **Conclusion**:
- Therefore, the correct answer to the question is that organisms are very much similar to each other at the level of **Species**.

### Final Answer:
The correct option is **Species**.
