Answer:
d. The leaders took advantage of the instability in the countries and of the people's needs for someone to be in charge
Explanation:
The manner in which Hitler in Germany, Mussolini in Italy, and Stalin in Russia came to power was very similar. All three countries where in terrible conditions, lack of unity, poverty, bad economy, and there was big despise towards the current leaders. These three political figures used this in their advantage, and they managed to convince the people that they will sort out their problems, make their countries great and powerful. Mussolini didn't really managed to achieve anything. Hitler managed to create an economic and military superpower, but pushed the country in a devastating war. Stalin did managed to create a global military power, but the people in the country lived in fear because he always used violence and brutality to achieve his goals.
