Animals are classified into hierarchical group. In which one of the following, the largest number of species are found?

Options

A. Genus
B. Order
C. Family
D. Class

Answer

To determine in which hierarchical group the largest number of animal species is found, we need to understand the classification system of animals. Here's a step-by-step breakdown:

### Step 1: Understand the Hierarchical Classification
Animals are classified into a hierarchical system that includes several levels:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species

### Step 2: Identify the Levels of Classification
In this system, each level represents a different rank of classification, with the Kingdom being the broadest category and Species being the most specific.

### Step 3: Determine the Number of Species in Each Level
- **Kingdom**: Contains the largest number of species.
- **Phylum**: Contains fewer species than the Kingdom.
- **Class**: Contains fewer species than the Phylum.
- **Order**: Contains fewer species than the Class.
- **Family**: Contains fewer species than the Order.
- **Genus**: Contains fewer species than the Family.
- **Species**: Contains the least number of species.

### Step 4: Analyze the Options
Given the options:
- **Genus** (6)
- **Order** (4)
- **Family** (5)
- **Class** (3)

We can see that:
- The **Kingdom** has the most species, but it is not listed in the options.
- Among the options provided, **Class** has the highest number (3), followed by **Family** (5), **Order** (4), and **Genus** (6).

### Step 5: Conclusion
Since the question asks for the group with the largest number of species, the correct answer is **Class**.

### Final Answer
The largest number of species is found in the **Class**.
