Respuesta :
The correct answer is C. Reference Pronoun.
Explanation:
The pronoun is used to replace the noun in a sentence. The pronoun can be placed as a reference when the noun was previously mentioned. In this particular case, the word "Them" is a reference to the words " Supernatural beings". So, in order to avoid the repetition of these words, we use the reference pronoun.
These supernatural beings brought with them three days and three nights of complete darkness, a harbinger of changes to come.
C. Reference Pronoun
A reference pronoun is a pronoun that refers to (or stands in for) a noun or noun phrase, also called an antecedent. In the sentence, "them" refers to the noun phrase (which also functions as the subject): "These supernatural beings", whose personal pronoun is "they".
The other options are incorrect because
- The possessive pronoun of "They" is "theirs", not "them" (A).
- "Them" never works as a subject in a sentence and the subject is already established: "These supernatural beings" (B)
- And lastly, "them" does not work as an object pronoun because it is not the object of the main verb ("brought).
