Assertion: Phylogenetic classification system provides more accurate arrangement of related taxa.
Reason: Phylogenetic classification is based on evolutionary relationship between the various organisms.

Options

A. If both assertion and Reason are true and the reason is a correct explanation of the assertion.
B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion and Reason are False.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the phylogenetic classification system provides a more accurate arrangement of related taxa. This means that it organizes organisms based on their evolutionary relationships, which should ideally reflect their true biological connections.

2. **Understanding the Reason**: The reason given is that phylogenetic classification is based on the evolutionary relationship between various organisms. This implies that the classification is grounded in the history of how different species have evolved from common ancestors.

3. **Exploring Phylogenetic Classification**: Phylogenetic classification involves creating phylogenetic trees that illustrate the evolutionary pathways and relationships among organisms. These trees are constructed using various traits observed in different organisms.

4. **Analyzing the Accuracy of Phylogenetic Classification**: The phylogenetic classification is considered more accurate because it not only categorizes organisms based on observable traits but also considers their evolutionary history. This allows for a better understanding of how species are related and how they have diverged over time.

5. **Conclusion on Assertion and Reason**: Since both the assertion and the reason are correct, we can conclude that the phylogenetic classification system does indeed provide a more accurate arrangement of related taxa, and this accuracy is due to its foundation in evolutionary relationships.

6. **Final Answer**: Both the assertion and the reason are true, and the reason is a correct explanation of the assertion.
