<p>We hope to send <b>your</b> tax documents to you by the end of the week.</p>
<p>The correct answer is (B) <b>your</b>.</p>
<p>In this sentence, the word "your" is used as a possessive pronoun. It is used to show that the tax documents belong to the person being addressed, which is "you".</p>
<p>(A) "you" is incorrect because it is a subject pronoun and cannot be used to show possession.</p>
<p>(C) "yours" is incorrect because it is a possessive pronoun used to show ownership, but it cannot be used directly before a noun like "tax documents". It would be correct to say "We hope to send the tax documents that are yours by the end of the week."</p>
<p>(D) "yourself" is incorrect because it is a reflexive pronoun used for emphasis or to refer back to the subject of the sentence. It does not indicate possession.</p>
