Which description explains the cause of vague pronoun references?

A. The antecedent of a pronoun is not clear.
B. The pronouns do not agree in number.
C. A pronoun is repeated in a sentence.
D. A pronoun replaces an antecedent.

A. The antecedent of a pronoun is not clear.

The correct answer is A. The antecedent of a pronoun is not clear.

Vague pronoun references occur when the antecedent, which is the noun or pronoun that a pronoun refers to, is not clear or easily identifiable. The antecedent is the concept or person that the pronoun replaces in a sentence. When the antecedent is not clearly stated or identifiable, it can lead to confusion and ambiguity in the meaning of the sentence. To avoid vague pronoun references, it is important to ensure that the antecedent is clear and can be easily understood by the reader or listener.
