Solution
The correct option is B uric acid The major excretory product in the cockroach is uric acid and hence it is called a uricotelic animal. The body cells discharge nitrogenous wastes into the haemolymph. The nitogenous wastes are absorbed by Malpighian tubules and converted into uric acid. The uric acid then enters into hindgut and is excreted out of the body.
