The correct answer is C) Jackson supporters resorted to tarnishing the reputation of the very ill William H. Crawford.
What was not a reason Andrew Jackson was denied the presidency in 1824 was "Jackson supporters resorted to tarnishing the reputation of the very ill William H. Crawford."
We are talking about the 10th election of 1824. This was a controversial election because none of the candidates won in the electoral vote. In the election competed John Quincy Adams, Andrew Jackson, William H. Crawford, and Henry Clay. That is why the US Congress had to decide the winner of the election. The House of Representatives elected Adams on February 9, 1825.
