Which of the following excretory structure is associated with gut of the organism?
Correct answer: C. Malpighian tubules
- A. Protonephridium
- B. Metanephridium
- C. Malpighian tubules
- D. Nephrons
Explanation
Malpighian tubules are insect excretory organs connected to the gut, where they release nitrogenous waste and help regulate salts and water. The likely distractor is nephrons, but nephrons are the excretory units of vertebrate kidneys and are not attached to the gut.
