Read the assertion and reason carefully to mark the correct option in question.
Assertion: Ammonia is generally excreted by diffusion across body surfaces or through gill surfaces (in fish) as ammonium ions.
Reason: Ammonia is readily soluble in water.

Reason: Ammonia is readily soluble in water.
Assertion-Reason relation
The nitrogen compounds through which excess nitrogen is eliminated from organisms are called nitrogenous wastes.
Ammonotelism is the process of eliminating ammonia. Aquatic animals such as amoeba, sponges, hydra, star fish, fresh/bony fishes, and tadpoles are ammonotelic animals.
Ammonia being soluble in water easily gets excreted out along with the waste water.
So, both the assertion and reason are correct. And reason is the correct explanation of the assertion.
Final Answer:
(A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
