Answer:
B. enemies or antagonists
Step-by-step explanation:
"Dreaming in Cuban" is a novel written by Cristina Garcia and it tells the story of three generations of a Cuban family, Cuban revolution, family affairs, emigration etc.
In this particular excerpt I can't seem to find the underlined word, but judging by given answers, I'm assuming it's a noun and "adversaries" seem like the only noun whose meaning might be unfamiliar to many.
Basically, adversary means antagonist, if we're talking about literature or film, the rival of the main character. In a broader sense, it denotes a rival, an enemy, person or thing that opposes someone.
