Answer 1

Answer: (B)

Uric acid

Uric acid is excreted in birds and reptiles. The mode of excretion of uric acid is uricotelism. Excretion in the form of uric acid and urates is helpful in conserving water. The birds excrete uric acid and urates so they are known as uricotelic organism. Uric acid is the least toxic and the least soluble in water. It can stored for longer duration in the body and it requires less water for excretion and thus helps to retain more water in the body.

So, the correct answer is 'Uric acid'.
