Find the correct statements from the followings
(A) Each rank or taxon, in fact represent a unit of classification
(B) Every step in taxonomic hierarchy represents a rank or category
(C) A taxonomic category is a part of overall taxonomic hierarchy
(D) Taxonomic categories are not distinct biological entities, they are only biological entities, they are only morphological aggregates

Options

A. A, B & D are correct
B. A, C & D are correct
C. A, B & C are correct
D. Only A and B are correct

Answer

To solve the question, we need to evaluate each of the four statements provided and determine which ones are correct regarding taxonomy and taxonomic categories.

### Step-by-Step Solution:

1. **Evaluate Statement (A)**: "Each rank or taxon, in fact, represents a unit of classification."
- **Analysis**: A taxon (plural: taxa) is indeed a unit of classification. Each rank in the taxonomic hierarchy (such as species, genus, family, etc.) represents a distinct unit used for classifying organisms.
- **Conclusion**: This statement is **True**.

2. **Evaluate Statement (B)**: "Every step in taxonomic hierarchy represents a rank or category."
- **Analysis**: The taxonomic hierarchy consists of various ranks or categories, such as kingdom, phylum, class, order, family, genus, and species. Each step in this hierarchy corresponds to a specific rank.
- **Conclusion**: This statement is **True**.

3. **Evaluate Statement (C)**: "A taxonomic category is a part of the overall taxonomic hierarchy."
- **Analysis**: Taxonomic categories (like species, genus, etc.) are indeed components of the broader taxonomic hierarchy. They help organize and classify living organisms within this hierarchy.
- **Conclusion**: This statement is **True**.

4. **Evaluate Statement (D)**: "Taxonomic categories are not distinct biological entities; they are only morphological aggregates."
- **Analysis**: Taxonomic categories are considered distinct biological entities. They are based on various criteria, including morphological and reproductive traits, but they are not merely aggregates; they represent specific classifications.
- **Conclusion**: This statement is **False**.

### Final Evaluation:
- Statements A, B, and C are correct.
- Statement D is incorrect.

### Correct Answer:
The correct statements are A, B, and C. Therefore, the correct option is **C**: "A, B, C are correct."
