A pollination mechanism some what similar to Anthocephalus, kigelia is seen in ?

Options

A. Najas
B. Cucurbita
C. Adansonia
D. Calotropis

Answer

To solve the question regarding the pollination mechanism similar to that of Anthocephalus and Kigelia, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Pollination Mechanism of Anthocephalus and Kigelia**:
- Both Anthocephalus and Kigelia have large, showy, and typically white flowers.
- These characteristics are indicative of plants that are pollinated by bats, a process known as chiropterophily.

2. **Analyze the Given Options**:
- The options provided are:
1. Najas
2. Cucurbita
3. Adenosonia
4. Calotropis

3. **Evaluate Each Option**:
- **Najas**: This is an aquatic plant that undergoes hydrophily (pollination by water). Therefore, it does not match the bat pollination mechanism.
- **Cucurbita**: Most cucurbits (like cucumbers and pumpkins) rely on insects for pollination (entomophily). This option is also incorrect.
- **Adenosonia**: This plant is known for having flowers that are pollinated by bats, making it a strong candidate for our answer.
- **Calotropis**: This plant is also pollinated by insects, as it has sticky pollen grains grouped into pollinia. Thus, this option is incorrect.

4. **Conclusion**:
- After evaluating all options, the only plant that shares a similar pollination mechanism with Anthocephalus and Kigelia is **Adenosonia**.

### Final Answer:
The correct answer is **Option 3: Adenosonia**.
