Solution
The correct option is C Birds
Uricotelism is ridding of an excess of uric acid. Uric acid is less toxic than ammonia so less amount of water is needed to remove it from the body. As terrestrial animals have to conserve water they use this mode of excretion where they pass dilute solution uric acid into the cloaca and water is absorbed and solid uric acid is eliminated from the body along with feces. Mostly Insects, lizards, and birds etc use this mode to remove waste from their body. Thus the correct answer is option C.
