Answer:
The correct answer is A: “And someone gave little Davy Hutchinson few pebbles.”
Step-by-step explanation:
In this excerpt, the only event which doesn't exemplify the short story's dark tone is the first option. As we can notice, in all the examples we have some words which are suggesting to something dark and negative, as, for example, murder, painful death, giving up.
In the first sentence, we cannot notice the dark tone because the author uses some positive and pleasant words, as for example, little Davy, a few pebbles, so we can see that he/she is describing a child with some pebbles.
