The theories that caused the U.S.S. Maine to explode while it sat in the Havana Harbor because they believe that Coal spontaneously combusted. It is believed that there were about 5 tons of ammunition on board.
The correct answer is D) Coal spontaneously combusted.
When the USS Maine initially sank, many newspaper writers immediately blamed the Spanish military for the Maine's destruction. This is due to the fact that the United States was in the Havanna Harbor trying to aid Cuban rebels against the Spanish. This initial blame put on Spain, later known as yellow journalism, resulted in the United States declaring war on Spain. This would lead to the brief Spanish-American War.
