Answer 2

One cause of the "Spanish-American War" is the belief that a Spanish mine had blown up the battleship Maine.

Option D

Explanation:

The reasons for the "Spanish-American" war were a lot but the two most important reasons for the war was the disappearance of Maine in Havana harbour and America's ruthless support to Cuba and Philippine because of their struggles against the Spanish rule.
