Most acceptable concept of species is :-

Options

A. Static concept
B. Biological concept
C. Typological concept
D. Genetic concept

Answer

### Step-by-Step Solution:

1. **Understanding the Concept of Species**:
- A species is typically defined as a group of organisms that can interbreed and produce fertile offspring. However, there are various concepts that define what constitutes a species.

2. **Reviewing Different Concepts of Species**:
- **Typological Concept**: This concept defines species based on fixed morphological traits. It assumes that species are static entities and does not account for evolutionary changes. This concept is limited because it does not consider the potential for interbreeding among individuals.
- **Biological Concept**: This is the most widely accepted concept of species. It defines species based on the ability of individuals to interbreed and produce fertile offspring. This concept emphasizes reproductive isolation, which helps maintain distinct species.
- **Genetic Concept**: This concept groups species based on genetic similarities and differences. While it uses sophisticated techniques like DNA fingerprinting, it is not always practical or feasible for classification purposes.

3. **Evaluating the Most Acceptable Concept**:
- The Biological Concept is favored because it considers the reproductive capabilities of organisms and allows for the understanding of species in the context of evolution and ecological interactions.
- The Typological and Genetic concepts have limitations that make them less acceptable in defining species.

4. **Conclusion**:
- Based on the evaluation of the different concepts, the most acceptable concept of species is the **Biological Concept**.

### Final Answer:
The most acceptable concept of species is the **Biological Concept**.
