Answer:
C.
Step-by-step explanation:
Dictators will be the only ones who they want to be in power. It is all about them. To do that, the top item on their to-do list of terror is by eliminating all opposition and ensuring that any future opposition cannot rise to power by cutting off all channels they can use to get there. They did this through propaganda, use of secret police, and prisons for political enemies known as gulags (most popularly from the Soviet Union).
It is also worth noting that even though it says fascism was against communism, it has all the hallmarks and shortcomings of it, as well as socialism.
