Verified by Toppr

The correct option is D Maxillary palps
  • Excretion in cockroach is primarly performed by Malpighian tubules. Each tubule is lined by glandular and ciliated cells. They absorb nitrogenous waste products and convert them into uric acid which is excreted out through the hindgut.
  • In addition, the fat body,nephrocytes and urecose glands also help in excretion.
  • While the maxillary palps are used for cleaning the antennae and also the front pair of legs.
So, the correct option is 'Maxillary palps'.
