Why Did Stalin and His Supporters Sponsor the First Five-Year

Why did Stalin and his supporters sponsor the first five-year plan?

A) They feared a gradual restoration of capitalism and, more importantly, wanted to catch up with the West and overcome traditional Russian "backwardness."
B) They believed that an organized cooperation with capitalism was essential and that the NEP lacked direction and purpose.
C) They modeled the five-year plan on the Meiji Restoration in Japan, combining industrialization with, in this case, the preservation of core Russian traditions.
D) They used the five-year plan, which Stalin knew would create a certain level of hardship and chaos, to create the ideal conditions for a wide-ranging purge of party and government officials.
