Answer:
B
Step-by-step explanation:
A symbol are often characters, settings, images, or other motifs that stand in for bigger ideas. Since this is multiple choice, B is the best choice. A and C wouldn't work because that is a fact shown in the excerpt. D wouldn't work because the excerpt doesn't give enough information on how the children could represent warriors and ghosts, so it doesn't fit. B is the best choice because "a crew of giggling little girls or round-eyed little boy crowded around the old man on the patio" gives a sense of child-like innocence, which Cheryl is bringing.
Hope this helps :)
