The body cells in cockroach discharge their nitrogenous waste in the haemolymph mainly in the form of Calcium carbonate, Ammonia, Potassium urate, or Urea?

The haemocoel in the cockroach is filled with haemolymph which contains metabolic waste mainly in the form of potassium urate. The excretory organ of cockroach is the malpighian tubules. It is found at the junction of the midgut and hindgut. It helps to remove the metabolic waste and maintains the osmoregulation. So, the correct answer is Potassium urate.
