Answer:
D.the story’s last sentence stating that the summer was over.
Explanation:
The last line, And the summer was over, ends her innocence completely. A harsher and more aware experience will take over Myop from that moment. The passage began with Myop a merry child with not a care in the world. But after the experience of seeing the gruesome decaying body of a dead man, she lays down the flowers she picked in her merry state beside the dead man. And the summer was over means that the innocence of the merry Myop had come to an end.
