Detailed explanation-1: -Final Answer: Malpighian tubules remove excretory matter from the hemolymph.

Detailed explanation-2: -Malpighian tubules help in removal of nitrogenous waste in some insects, arachnids, etc.

Detailed explanation-3: -So, the correct answer is-haemolymph.

Detailed explanation-4: -Malpighian tubules are found in the posterior regions of insects, where they work with glands in the rectum to excrete waste and maintain osmotic balance.

Detailed explanation-5: -General mode of action Pre-urine is formed in the tubules, when nitrogenous waste and electrolytes are transported through the tubule walls. Wastes such as urea and amino acids are thought to diffuse through the walls, while ions such as sodium and potassium are transported by active pump mechanisms.
