Answer:
Option (1)
Explanation:
The amount of carbon present in the ocean is inversely proportional to the pH level of water. This CO₂ amount present in the atmosphere may rise because of various types of human activities, that results in the increasing amount of dissolved CO₂ in the oceans. This in turn, again decreases the pH level of water. This water when reduces, it becomes saturated with the CO₂ and it also diminishes the source of calcium carbonate.
The increase in the ocean acidification leads to the significant reduction of the reef-building corals. As a result of which the temperature of the water increases and they are not able to assemble their skeletal parts.
Hence, the correct answer is option (1).
