the correct answer is option c. elenita versus "early puerto rican decor" is the best example, out of all the options, of a cultural conflict. a cultural conflict is defined as what happens when different cultures, that have different values and believes, clash. elenita not liking or accepting the puerto rican style of decoration, would represent that she does not identify herself with the puerto rican culture, therefore does not want to have decorations influenced by that culture.
