Answer:
The correct answer is D. They increased the public's anger toward Spain.
Step-by-step explanation:
In January 1898, the American battleship USS Maine left Key West for Havana, as it went there in the context of the Cuban War of Independence, to protect American property and citizens on the island, which was in a state of political upheaval that threatened the interests of the nation in said territory.
Once there, a few weeks after arriving, the Maine sank after an explosion in the port of Havana on February 15, 1898. This explosion was initially attributed to a Spanish attack by means of a marine mine, and it was used by the American press to stir up the warlike atmosphere in the United States, which finally led to war later that year after growing popular pressure that wanted revenge against Spain. The explosion killed 266 people, about two-thirds of the total crew.
