It caused the delegates to vote in 1861 that Louisiana would secede.
Answer: Option D.
<u>Explanation:</u>
On January 8, 1861 the governor of Louisiana, Thomas Overton Moore organised a convention which was about the secession of Louisiana. He ordered a militia arsenal to occupy the United States arsenal.
He acted aggressively to engineer the secession of Louisiana from the union by a convention. Only five percent of the public was represented in the convention and the delegates voted 113 to 17 to secede from the union. And therefore there was secession of Louisiana.
