Answer:
It's A.
Explanation:
The others just don't make sense. I really don't know how to explain it better.
Rousseau talks about some of his experiences from he was younger and he talks about how he started to get involved in literature, he even talked about how some experiences made him very sad for a long period of time but that same sadness became happiness when he became older.

Answer:
the overall mood.
The tone of a story is how the author shows the general attitude in the story. So if the story seems sad through the words, you can assume the rest of the story will be as well.
Think of it as a horror movie. Weird or scary things happen in the beginning, and that general tone/theme will continue throughout.
