Why Is the Secretion of Uric Acid Beneficial to Organisms

Why is the secretion of uric acid beneficial to organisms that live in hot and dry environments?

A) Uric acid has poor solubility in water so it will become concentrated during excretion as well as being relatively nontoxic.
B) Uric acid has a high degree of solubility in water so it will become concentrated during excretion as well as being relatively nontoxic.
C) Uric acid has poor solubility in water so it will become concentrated during excretion which allows the organism to use it as a defense mechanism.
D) Uric acid can be readily reabsorbed by the urinary system so it decreases the amount of waste produced by the organism.
