Verified by Experts

The correct Answer is:
B
Ammonia is the main nitriogenous waste. It is soluble in water and highly toxic. A large amount of water is requires for its excretion. Tadpole is aquatic and lives in plenty of water so, nitrogenous wastes in tadpole are eliminated as ammonia. Frog being amphibious excretes its nitrogenous wastes as urea.
