C. They lives in same habitat
D. (2) and (3) both

Answer

To determine when two local populations become sister populations, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Local Populations**:
- Local populations refer to groups of organisms of the same species that live in a specific area.

2. **Defining Sister Populations**:
- Sister populations are defined as different populations of the same species that are geographically separated. This means they belong to the same species but are found in different locations.

3. **Analyzing the Options**:
- **Option 1**: They have the same species.
- This option is correct because sister populations must consist of the same species.
- **Option 2**: They have different species.
- This option is incorrect because sister populations must be of the same species.
- **Option 3**: They live in the same habitat.
- This option is also incorrect because sister populations live in different habitats.
- **Option 4**: Two and three both.
- This option is incorrect since both options two and three are wrong.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option 1**: They have the same species.

### Final Answer:
Two local populations become sister populations when they have the same species.
