The correct response is: The pope refused to annul Henry's marriage and allow him to remarry.
Henry VIII sought an annulment of his marriage to Catherine of Aragon because she had not provided him with a male heir, and he wished to marry Anne Boleyn. The pope's refusal to grant this annulment was a key factor in Henry's conflict with the papacy and ultimately led to the English Reformation and the establishment of the Church of England.
