Answer:
C. the continued belief that the key was stolen
Explanation:
The statement about the passage that best reflects the influence of a totalitarian dictator is "the continued belief that the key was stolen"
In totalitarianism, it is believed that all control lies in the hands of the dictator. Therefore, it's very easy to attribute whatever happens to him.
So, the continued belief that the key was stolen by Snowball shows that Snowball has control over the key and anything that happens to the key is likely to be attributed to him.
In totalitarianism, the influence of the totalitarian is seen in the things under his control.
