Answer:
b. an adequate supply of consumer goods.
Explanation:
Communism is the philosophical, social, political and economic form of governance where factors of production are owned by the state.
There are no social classes as everyone is on the same class.
Since factors of production are state controlled there is no motivation by the citizens to improve production for aim of earning profit.
This results in frequent shortages of consumer goods in communist countries.
The government has to ration available food to the citizens.
Communist countries include Cuba, China, and Vietnam
