Which of the following statements regarding biodiversity hotspots are incorrect?
(i) High endemism
(ii) High level of species richness
(iii) Total number is 34 in the world
(iv) Five of these occur in India
(v) High alien species invasion
(vi) Cover less than `2%` of the earth's land area, but if properly conserved, they can reduce extinctions by about `30%`
(a) (i) and (ii)
(b) (iv) and (v)
(c) iv), (v) and (vi)
(d) (iii), (iv), (v) and (vi)

Options

A. (i) and (ii)
B. (iv) and (v)
C. (iv), (v) and (vi)
D. (iii), (iv), (v) and (vi)

Explanation

To determine which statements regarding biodiversity hotspots are incorrect, let's analyze each statement step by step:

1. **High endemism**: Biodiversity hotspots are characterized by a high level of endemism, meaning they contain many species that are not found anywhere else in the world. This statement is **correct**.

2. **High level of species richness**: Biodiversity hotspots also have a high level of species richness, which refers to the number of different species present in a given area. This statement is **correct**.

3. **Total number is 34 in the world**: Currently, there are indeed 34 recognized biodiversity hotspots around the world. This statement is **correct**.

4. **Five of these occur in India**: While India is home to several biodiversity hotspots, there are only **four** recognized hotspots: the Western Ghats, Indo-Burma, Himalaya, and Sundaland. Therefore, this statement is **incorrect**.

5. **High alien species invasion**: Biodiversity hotspots are typically areas that are rich in native species and are often threatened by invasive alien species. However, the statement implies that these hotspots have a high level of alien species invasion, which is misleading. This statement is **incorrect**.

6. **Cover less than 2% of the earth's land area, but if properly conserved, they can reduce extinctions by about 30%**: This statement is **correct**. Biodiversity hotspots cover less than 2% of the Earth's land area, and effective conservation efforts in these areas can significantly reduce extinction rates.

Now, summarizing the analysis:
- **Correct Statements**: (i), (ii), (iii), (vi)
- **Incorrect Statements**: (iv), (v)

Thus, the incorrect statements are (iv) and (v). Therefore, the correct answer is **(b) (iv) and (v)**.
