Options B and C.
Option A is not one of the correct answers because communism is quite the opposite: the government controls nearly everything in economy.
Competition in the marketplace is more intense in capitalistic societies, since people want more money and will innovate more to achieve that money.

Similarly, people won't be as inclined to work hard in communist societies since everyone gets the same amount of pay regardless of how hard they work.
