Which one has become endangered due to extinction of Dodo (Raphus cucullatus)

Options

A. Sideroxylon grandiflorum
B. Chrysanthemum
C. Cinchona
D. Bacillus thuringiensis.

Explanation

**Step-by-Step Solution:**

1. **Identify the Extinct Species**: The question refers to the Dodo, scientifically known as Raphus cucullatus, which became extinct in the 17th century.

2. **Understand the Ecological Role of the Dodo**: The Dodo was known to eat the fruits of a specific tree. This tree is crucial for the germination of its seeds, as the seeds require passage through the Dodo's digestive system to germinate.

3. **Identify the Tree Related to the Dodo**: The tree that relies on the Dodo for seed germination is known as Sideroxylon grandiflorum, commonly referred to as the Dodo tree.

4. **Hypothesis by Stanley Temple**: Stanley Temple hypothesized that the extinction of the Dodo led to the endangerment of Sideroxylon grandiflorum because without the Dodo, the seeds of this tree could not germinate properly.

5. **Conclusion**: Therefore, the species that has become endangered due to the extinction of the Dodo is Sideroxylon grandiflorum.

**Final Answer**: Sideroxylon grandiflorum
