I believe the answer is: B.dictator comes to power and convinces the populace that only s/he will bring much needed safety or prestige to the country
In a fascist government, the citizens is required to follow all the orders made by the government without any chance to criticise it. This could only happen if the leader is a dictator who seek absolute power, along with the naivety of the citizens to blindly follow such leaders and let their freedom be taken away.
