Answer:
They describe Pau Amma’s impact on the sea and the animals.
Step-by-step explanation:
Rudyard Kipling's children's story "The Crab That Played with the Sea" is a story about a crab who refuses to obey the instructions of the Eldest Magician. The story is about how the Eldest Magician instructed all the animals to obey Man, which Pau Amma, the crab, refused.
In the given extract from the story, we can see that Pau Amma has been caught doing things that affected those around him. When he went out of the sea, the beaches became bare and fishes die. And when he returns to his cave, it floods the areas around him. This is the impact of Pau Amma's act of moving in and out of the sea.
Thus, the correct answer is the third option.
