The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Excretion in Cockroaches:** - Excretion is the process by which waste products are removed from the body. In cockroaches, this process involves specific organs. 2. **Evaluating the Options:** - The question provides four options regarding the organs involved in excretion in cockroaches. 3. **Analyzing Each Option:** - **Option 1: Nephridium** - Nephridia are excretory organs found in some invertebrates and are primarily associated with annelids, not cockroaches. Therefore, this option is incorrect. - **Option 2: Parotid Gland** - The parotid gland is a type of salivary gland that secretes saliva, which is not involved in excretion. Thus, this option is also incorrect. - **Option 3: Coxal Gland** - Coxal glands are present in some arthropods and do play a role in excretion, but they are not the primary excretory structures in cockroaches. Hence, this option is incorrect. - **Option 4: Malpighian Tubules** - Malpighian tubules are the primary excretory structures in cockroaches. They are responsible for removing waste products from the hemolymph (the blood equivalent in insects) and excreting them as uric acid. This option is correct. 4. **Conclusion:** - Based on the analysis, the correct answer to the question "Excretion in Cockroach occurs through" is **Malpighian Tubules**. **Final Answer:** Excretion in cockroach occurs through **Malpighian Tubules**. ---
