Explanation
Correct answer: C.
Choice C is the best answer. The convention being tested is the use of plural and possessive nouns. The plural nouns “stories” and “immigrants” correctly indicate that the memoir tells multiple stories of multiple immigrants.
Why the other choices are wrong
Choice A
Choice A is incorrect because the context requires the plural noun “stories,” not the singular possessive noun “story’s.”
Choice B
Choice B is incorrect because the context requires the plural nouns “stories” and “immigrants,” not the singular possessive noun “story’s” and the plural possessive noun “immigrants’.”
Choice D
Choice D is incorrect because the context requires the plural nouns “stories” and “immigrants,” not the plural possessive noun “stories’” and the singular possessive noun “immigrant’s.”
