Answer:
The correct answer is letter "B": no circumstances exist that allow a tax preparer to endorse or otherwise negotiate a taxpayer's federal tax refund check.
Step-by-step explanation:
Tax refund checks are not endorsable under any circumstance. Taxpayers can provide a Power of Attorney to other individuals or third parties so they can receive the taxpayer's confidential information but not even with a Power of Attorney the individual can endorse a tax refund check.
