The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks how a cockroach moves on a rough surface. To answer this, we need to identify the anatomical structures that facilitate movement on such surfaces. 2. **Identifying the Options**: The options given are: - A. Aroleum - B. Pulvulus - C. Claw - D. Plantulate 3. **Analyzing the Structures**: - **Aroleum**: These are adhesive pads located at the distal end of the cockroach's legs. They help in gripping surfaces, especially rough ones. - **Pulvulus**: This term generally refers to a cushion-like structure but is not specifically known for aiding movement on rough surfaces in cockroaches. - **Claw**: While claws can assist in gripping, they are not the primary structure for movement on rough surfaces in cockroaches. - **Plantulate**: This term is not commonly associated with cockroach movement. 4. **Conclusion**: The aroleum pads are specifically designed to adhere to various surfaces, including rough ones, which allows cockroaches to move effectively. Therefore, the correct answer is **A. Aroleum**. 5. **Final Answer**: Cockroach moves on the rough surface by **Aroleum**. ---
