Answer:
The right answer is that the Maine was sent to Cuba in 1898 to protect the lifes and the properties and interests of American citizens during a Cuban rebellion against Spain that had started in January.
Step-by-step explanation:
The battleship was anchored in the Havanna harbor. A mysterious explosion occured, sinking the ship on February 14. It killed 260 people out of a 400- member crew. Failed diplomatic efforts to elicit an explanation from Spain and rejection of Spanish brutality against Cubans by the American public led to a declaration of war.
