Which of the following is the basic unit of classification?

Options

A. Individual
B. Population
C. Species
D. genus

Answer

To determine the basic unit of classification among living organisms, we can follow these steps:

### Step 1: Understand the Hierarchical Classification System
Living organisms are classified into a hierarchical system consisting of seven main categories. These categories are organized from the broadest to the most specific. The seven categories are:
1. Kingdom
2. Phylum
3. Class
4. Order
5. Family
6. Genus
7. Species

### Step 2: Identify the Basic Unit of Classification
In this classification system, the most specific and fundamental category is the species. A species is defined as a group of organisms that can interbreed and produce fertile offspring. It represents the basic unit of classification because it encompasses all individuals that share common characteristics and genetic similarities.

### Step 3: Analyze the Given Options
Now, let’s evaluate the options provided in the question:
- **Option 1: Individual** - This refers to a single organism and is not a classification category.
- **Option 2: Population** - This is a group of individuals of the same species living in a particular area, but it is not the basic unit of classification.
- **Option 3: Species** - This is the correct answer as it is the basic unit of classification.
- **Option 4: Genus** - This is a category above species and therefore cannot be the basic unit.

### Conclusion
Based on the analysis, the basic unit of classification is **Species**.
