The answer is <u>1) Anywhere in the sentence.</u>
An antecedent is a word or words that a pronoun refers to. To make it clear, some pronouns are "we", "they", "she", "her", etc.
For example, in the sentece: <em>My </em><em>friends</em><em> are coming to my house today so I will prepare some food for </em><em>them</em><em>. </em>"Friends" is the antecedent, and "them" is the pronoun, which refers to the antecedent.
And although we tend to use pronouns after the antecedent has been placed, it is also correct to use the pronouns before the antecedent. For example:
<em>Following </em><em>his</em><em> arrival in South America, </em><em>Columbus</em><em> sought to subjugate the Indians tribes.</em>
"His" is the pronoun, and "Columbus" is the antecedent.
<u>All of this to clarify that the pronoun can be placed after and before the antecedent. So, it could be placed anywhere in the sentence. </u>
However, if we were talking about a long paragraph, it would be preferable that pronouns are close to the antecedent to avoid confusion and we don't lose track of what's being said.
