Options

A. digestion
B. locomotion
C. respiration
D. reproduction

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure**: The Arolium is a specific structure found at the distal end of the legs of a cockroach, particularly on the tarsus (the last segment of the leg).

2. **Identifying the Characteristics**: The Arolium is described as a smooth and flexible pad. It is broad and triangular in shape, which allows it to function effectively.

3. **Function of Arolium**: The primary function of the Arolium is to act as an adhesive organ. This means it helps the cockroach in adhering to surfaces, which is crucial for its movement.

4. **Role in Locomotion**: The Arolium aids in locomotion by allowing the cockroach to grip onto various surfaces. This is particularly important for climbing and moving on smooth or vertical surfaces.

5. **Eliminating Other Options**: The other options provided (digestion, respiration, and reproduction) do not relate to the function of the Arolium. It is specifically adapted for locomotion.

6. **Conclusion**: Therefore, the correct answer to the question "Arolium of Cockroach helps in" is locomotion.

**Final Answer**: The Arolium of the cockroach helps in locomotion.
