Answer: Carbonic acid
Explanation:
The process of respiration of the terrestrial organism and marine organism leads to the exchange of gases. Due to exchange of gases, there is an entrance of carbon dioxide into the ocean and oxygen out of the ocean.
The addition of carbon dioxide into the water causes acidification of water and oxygen is diffused out of the water.
Hence, the product formed at Point A is carbonic acid.
