Right answer: Subtropical
This is according to the Köpen classification.
It is important to note this is due to Cuba’s geographical position, since its latitude is close to the Tropic of Cancer. This is the main reason that regulates the reception of very high values of solar radiation throughout the year and a warm climate.
In addition, this island is located on the border between areas of tropical circulation and extra tropical circulation, so it receives the influence of both, depending on the season.
Therefore the right option is A.
