How did the development of communism in cuba affect its economy

C) The Soviet Union agreed to buy large amounts of Cuban sugar.

Explanation:

The Cuban Revolution (January 1st, 1959) drove Fidel Castro to power. The United States reacted by increasing the economic embargo. This led Cuba to desperately look for new markets in order to avoid an economic collapse. Castro requested help from the Soviet Union and Khrushchev allowed a temporary trade of Cuban sugar for Soviet combustible. This agreement was fundamental in sustaining the Cuban economy for many years.
