Answer

To solve the question, "Ten pairs of spiracles with trachea are present in," we will analyze the options provided: starfish, cockroach, earthworm, and frog.

### Step-by-Step Solution:

1. **Understanding Spiracles and Trachea**:
- Spiracles are small openings that lead to the tracheal system, which is responsible for gas exchange in certain animals.
- The trachea are tubes that carry oxygen directly to the tissues of the organism.

2. **Identifying the Organisms**:
- **Starfish**: Starfish do not have spiracles or a tracheal system; they use a water vascular system for respiration.
- **Earthworm**: Earthworms respire through their skin and do not have spiracles or a tracheal system.
- **Frog**: Frogs primarily use lungs for respiration and do not have spiracles in the same way insects do.
- **Cockroach**: Cockroaches have a well-developed tracheal system that includes ten pairs of spiracles.

3. **Conclusion**:
- Based on the above analysis, the organism that has ten pairs of spiracles with trachea is the **cockroach**.

### Final Answer:
