The correct answer is Option 4, that is, all the three given statements are correct. Let`s explore each one:

1. "Most of the world’s coral reefs are in tropical waters." - This statement is correct. Coral reefs are formed in tropical marine environments where the water is warm and clear, and there`s a lot of sunlight.

2. "More than one-third of the world’s coral reefs are located in the territories of Australia, Indonesia and Philippines." - This statement is correct as well. Australia is home to the Great Barrier Reef, the world’s largest coral reef. Indonesia and the Philippines, due to their relevant geographic locations, also harbor substantial amount of coral reefs.

3. "Coral reefs host far more number of animal phyla than those hosted by tropical rainforests." - This statement is also correct. While rainforests are rich in biodiversity, coral reefs are known as the "rainforests of the sea" because they host such a high concentration of life, including a variety of animal phyla.

In summary, all the given statements are accurate, making Option 4 the correct answer.
