- A. Humans - Kidneys, sebaceous glands and tear glands
- B. Earthworm - Pharyngeal, integumentary and septal nephridia
- C. Cockroach - Malpighian tubules and enteric caeca
- D. Frog - Kidneys, skin and buccal epithelium
Explanation
Kidneys are the primary excretory organs in humans. They filter waste products and excess substances from the blood to form urine, which is then eliminated from the body. Sebaceous glands and tear glands do not serve as excretory organs; they have different functions related to skin and eye health, respectively.
