339677 Select the correct statement from the following:
(A) In most of the invertebrates, excretory structures are in complex tubular forms.
(B) Vertebrates have simple tubular organ as excretory structure like kidney.
(C) Protonephridia is primarily concerned with excretion.
(D) Protonephridia are excretory structure in rotifers, some annelids and cephalochordates (Amphioxus).

339678 Assertion :
Deamination takes place in the hepatocytes producing \(\mathrm{NH}_{3}\).
Reason :
Ornithine cycle combines \(\mathrm{NH}_{3}\) and \(\mathrm{CO}_{2}\) to form urea in the hepatocytes.

339679 Statement A :
Ammonia is the least toxic form and requires large amount of water for its elimination.
Statement B :
Uric acid, being the most toxic, can be removed with a minimum loss of water.
