Solution

The correct option is D Uric acid
A uricotelic organism excretes uric acid or its salts as a result of deamination. Among the three major forms of excretion of nitrogenous waste in organisms (the others being ammonotelism and ureotelism), uric acid is the least toxic and the least soluble in water. Uricotelic organisms typically have white pasty excreta. These include terrestrial arthropods (including insects), lizards, snakes, and birds.
So, the correct answer is option B.
