Coral reefs are home to some of the most A. varied forms of life in the world.

In an informative text, the author's purpose to inform by using facts; adjectives like 'peculiar' and 'amazing' depict the author's opinion, not facts, so these answer choices can be ruled out. Also, "thousands of different" indicates that there is a wide variety of plants and animals, so the word 'common' would not be accurate; therefore, the most appropriate answer choice is A. varied.

Use the information given after the sentence.

The sentence after states that 'thousands of different plants and animals' are in the coral reefs. This indicates a vast number of forms of life in the world, so you want to use a word that can be used to represent the massive number.

The word that completes this purpose is A. varied.
