(D) The excretory system of a cockroach consists of Malpighian tubules,which are the primary excretory organs. Statement $(i)$ is correct.Malpighian tubules absorb nitrogenous waste products from the haemolymph and convert them into uric acid. This uric acid is then excreted out through the hindgut. Statement $(ii)$ is correct.Besides Malpighian tubules,other structures like the fat body,nephrocytes,and urecose glands also assist in the process of excretion in cockroaches. Statement $(iii)$ is correct.Since all three statements are correct,the correct option is $(D)$.
