Answer:
C. The US had a military base at Guantanamo Bay.
D. The US had many economic interests in Cuba.
Step-by-step explanation:
It's not A because let's be honest, that's a very dum answer
It's not B because that's an even more dum answer
So since there is more than one answer, it would be both C and D.
C because the US till this day has a military base in Cuba called Guantanamo Bay, where they send criminals.
D because Cuba was like "America's Playground" as it was controlled by them prior to their independence. Considering how close it was, it would be a good trading point.
Hope this helped m8!
