Which of the following is pollinated by bats ?

Options

A. Kigella
B. Ophrys
C. Salvia
D. Helianthus

Answer

To determine which plant is pollinated by bats, we need to understand the concept of chiropterophily, which refers to bat pollination. Let's analyze the options provided:

1. **Kigelia pinnata**: This plant is known to be pollinated by bats. It has large, tubular flowers that are often open at night, attracting nocturnal pollinators like bats.

2. **Ophiris**: This plant is primarily pollinated by bees. Therefore, it is not the correct answer.

3. **Salvia**: This plant is typically pollinated by birds, not bats. Hence, it is also not the correct answer.

4. **Nephthytis and Helminthus**: Helminthus does not have bat pollination associated with it. Thus, it is not the correct answer.

Based on this analysis, the only plant from the options that is pollinated by bats is **Kigelia pinnata**.

### Final Answer:
**Kigelia pinnata** is the plant that is pollinated by bats.
