Pronoun “WHICH” has more than one antecedent to which it refer to, thus making it an incorrect or unclear pronoun.
Explanation:
Pronouns are used in place of noun and must refer to its antecedent, i.e. something that is already stated in the sentence. If there are more than one antecedents in a sentence, then it makes the pronoun either an ambiguous pronoun or unclear/incorrect pronoun.
The solution is to rephrase/rewrite the sentence or removing the ambiguity to make the reader understand the sentence clearly.
