Species is

Options

A. Population of individuals having same genotypes and phenotypes
B. A group of individuals inhabiting a geographical area
C. A group of interbreeding populations
D. Population of one type

Explanation

### Step-by-Step Solution:

1. **Understanding the Concept of Species**:
- A species is defined as a group of similar organisms that can interbreed and produce fertile offspring. This is a fundamental concept in biology that helps categorize and understand the diversity of life.

2. **Analyzing the Options**:
- **Option 1**: "Population of individuals having the same genotypes and phenotypes."
- This option suggests that all individuals in a species must have identical genetic and physical traits. However, this is not accurate as variations exist within a species.

- **Option 2**: "A group of individuals inhabiting the geographical area."
- This option implies that any group of organisms in a specific area constitutes a species. However, different species can coexist in the same geographical area, making this definition too broad.

- **Option 3**: "A group of interbreeding populations."
- This option correctly identifies that a species consists of populations that can interbreed with one another, which is a key characteristic of a species.

- **Option 4**: "Population of one type."
- This option is vague and does not adequately define a species, as it does not address the interbreeding aspect.

3. **Conclusion**:
- After analyzing all the options, the most accurate definition of a species is given by **Option 3**: "A group of interbreeding populations." This definition highlights the ability of individuals within a species to mate and produce viable offspring.

### Final Answer:
A species is a group of interbreeding populations.
