Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Uricotelic organisms are those which remove nitrogenous waste in the form of uric acid. Examples include lizards, snakes, birds. As compared to ammonia and urea, uric acid is the least toxic and the least soluble in water. Hence, birds are obliged to uricotelic as they have very limited access to water.
Thus, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.'
