Which of the following is the correct hierarchial sequence ?

Options

A. Phylum-Class-Order-Family
B. Genus-Species-Order-Family
C. Phylum-Division-Family-Class
D. Division-Order-Class-Genus

Answer

To determine the correct hierarchical sequence in biological classification, we need to understand the standard order of taxonomic ranks. Here’s the step-by-step solution:

### Step 1: Understand the Taxonomic Hierarchy
The taxonomic hierarchy is a system used to classify and organize living organisms. The standard sequence, starting from the broadest category to the most specific, is as follows:
1. Kingdom
2. Phylum
3. Class
4. Order
5. Family
6. Genus
7. Species

### Step 2: Analyze the Options
Now, we need to analyze the options provided in the question to identify which one follows the correct hierarchical sequence.

- **Option A**: Phylum, Class, Order, Family
- **Option B**: Genus, Species, Order, Family
- **Option C**: Class, Family, Order, Genus
- **Option D**: Division, Order, Class, Genus

### Step 3: Identify the Correct Sequence
From the analysis:
- **Option A** is incorrect because it starts with Phylum and does not follow the correct order.
- **Option B** is incorrect because it starts with Genus and Species, which are lower in the hierarchy.
- **Option C** is incorrect because it places Class after Family and Order, which is not correct.
- **Option D** is incorrect because it starts with Division and does not follow the correct order.

### Step 4: Conclusion
None of the options provided follow the correct hierarchical sequence. However, if we were to correct the sequence, it should be:
1. Kingdom
2. Phylum
3. Class
4. Order
5. Family
6. Genus
7. Species

### Final Answer
The correct hierarchical sequence is:
- Kingdom > Phylum > Class > Order > Family > Genus > Species
