Solution
The correct option is D Urea
A ureotelic organism excretes excess nitrogen as urea. It is one of the three major forms of excretion of nitrogenous waste in organisms, the others being ammonotelism and uricotelism. Urea is less toxic than the ammonia excreted by ammonotelic organisms. It requires 0.05 L of water to excrete 1 g of nitrogen, approximately only 10% of that required in ammonotelic organisms. Ureotelic organisms include cartilaginous fish, some bony fish, adult amphibians and mammals. Humans can be described as being ureotelic organisms. Thus, option B is correct.
