The correct sequence of taxonomic hierarchy in eukaryotes is :
(a) phylum-class-order-family-genus-species
(b) class-order-phylum-family-genus-species
(c) phylum-order-class-family-genus-species
(d) phylum-family-class-order-genus-species

Options

A. phylum-class-order-family-genus-species
B. class-order-phylum-family-genus-species
C. phylum-order-class-family-genus-species
D. phylum-family-class-order-genus-species

Explanation

To determine the correct sequence of taxonomic hierarchy in eukaryotes, we need to understand the standard classification levels. Here’s a step-by-step breakdown of the taxonomic hierarchy:

1. **Phylum**: This is the first level we will consider in the options provided. It is a major taxonomic category that groups together related classes.

2. **Class**: Following phylum, the next level is class. Each phylum can be divided into multiple classes.

3. **Order**: After class, we have order. Each class can be further divided into orders.

4. **Family**: The next level is family. Each order can consist of multiple families.

5. **Genus**: Following family, we have genus. Each family can contain multiple genera (plural of genus).

6. **Species**: Finally, the last level is species, which is the most specific classification and represents individual organisms that can breed and produce fertile offspring.

Now, putting these levels together, the correct sequence of taxonomic hierarchy in eukaryotes is:

**Phylum → Class → Order → Family → Genus → Species**

Thus, the correct answer is:

**(a) phylum-class-order-family-genus-species**
