Answer: C
Corals are confined to low and middle latitudes because of suitable temperature conditions.
Reef-building corals need warm water that does not fall below about 20°C, with the best growth between about 23°C and 29°C. Water that warm is found only in the tropical and subtropical seas, roughly between 30°N and 30°S, and along coasts washed by warm currents. Cold currents keep reefs away even from tropical coasts, as on the western side of the continents.
The other options do not explain the pattern. Heavy rain and fresh river water dilute the sea and kill corals, so high rainfall is a hindrance. Hot and humid air describes the climate on land, not the water corals live in. Corals do need normal salinity, but suitable salinity is found in all latitudes, so it is not what limits them to warm seas.
