An exotic species that is introduced to a new area, spreads rapidly and eliminates native species is called
(a) Immigrant species
(b) Invasive species
(c) Destructive species
(d) None of these

Options

A. immigrant species
B. invasive species
C. destructive species
D. none of these

Explanation

To solve the question, we need to identify the correct term for an exotic species that is introduced to a new area, spreads rapidly, and eliminates native species. Let's analyze the options step by step:

1. **Understanding the Question**: The question describes an exotic species that is introduced to a new area and has negative impacts on native species by spreading rapidly and eliminating them.

2. **Analyzing Option A - Immigrant Species**:
- Immigrant species typically refer to species that move into a new area but do not necessarily have a harmful impact on native species. This term does not imply rapid spread or elimination of natives. Therefore, this option is not correct.

3. **Analyzing Option B - Invasive Species**:
- Invasive species are defined as non-native species that, when introduced to a new environment, spread rapidly and can cause harm to native species and ecosystems. This matches the description given in the question. Thus, this option is likely correct.

4. **Analyzing Option C - Destructive Species**:
- While "destructive species" may imply harm, it is not a standard term used in ecology to describe species that invade and eliminate native species. This option does not fit the definition provided in the question.

5. **Analyzing Option D - None of These**:
- Since we have identified option B as a suitable answer, this option can be eliminated.

6. **Conclusion**: Based on the analysis, the correct answer to the question is **(b) Invasive species**.

### Final Answer:
(b) Invasive species
