D. its geographic location near Panama
Step-by-step explanation:
The qualities about Puerto Rico that made it a strategically appealing territory for the U.S. include:
B. its use as a naval base
D. its geographic location near Panama
Puerto Rico's strategic location in the Caribbean and its use as a naval base were significant factors in its importance to the United States. Additionally, its proximity to the Panama Canal (though not directly adjacent) added to its strategic value. The tropical climate and the state of its economy were not the primary factors in its strategic appeal.
