Ask EduPadi AI for a detailed answer
Correct Option: D
The correct answer is Nephridium. Here's why:
- Nephridia: These are the primary excretory organs in earthworms. They filter waste products from the body fluids and eliminate them.
- Contractile vacuole: This is involved in osmoregulation (water balance) and waste removal in some protists, not earthworms.
- Flame cells: Flame cells are excretory structures found in flatworms.
- Malpighian tubule: Malpighian tubules are excretory structures found in insects and other arthropods.
