Options

A. Orchids
B. Trapa
C. Podostemon
D. Screwpine

Answer

### Step-by-Step Solution:

1. **Understanding Clinging Roots**: Clinging roots are specialized roots that help certain plants attach themselves to other structures for support rather than for nutrient absorption.

2. **Identifying the Type of Plants**: Clinging roots are primarily found in epiphytes. Epiphytes are plants that grow on other plants (usually trees) but do not harm them. They do not have mechanical tissues, which means they cannot support themselves and rely on other plants for physical support.

3. **Function of Clinging Roots**: The main function of clinging roots is to anchor the plant to another plant, such as a tree trunk or branch, allowing the epiphyte to access sunlight and air while remaining elevated above the ground.

4. **Examples of Plants with Clinging Roots**: A well-known example of epiphytes that possess clinging roots is orchids. Orchids can often be found growing on trees, where their clinging roots help them stabilize and secure themselves.

5. **Conclusion**: Based on the information provided, clinging roots are found in epiphytes, with orchids being a prime example of such plants.

### Final Answer:
Clinging roots are found in **epiphytes**, such as **orchids**.
