c. spain claimed responsibility for the explosion.

d. it happened during the first naval battle of the war.

No one knew for certain the reason for the explosion.

Option: (A)

Explanation:

Though it was claimed by the American newspapers at the beginning that Spain was responsible for the sinking of USS Maine, the later investigation failed to find any evidence that pointed at Spain for the happening. The fact that there was a mine explosion beneath the bottom of the ship clarified that the reason for sinking was an active mine dropped in the waters close to the harbor. But the ones responsible for leaving the mine there have never been found.
