Final answer:
The Soviet government sold Ukrainian grain abroad during the 1932-1933 Holodomor to fund its industrial development as part of Stalin's Five-Year Plan. The correct option is C.
Step-by-step explanation:
During the Holodomor in Ukraine in 1932-1933, the Soviet government, under the leadership of Joseph Stalin, sold Ukrainian grain outside of the USSR to pay for industrial development. This was part of Stalin's Five-Year Plan, which aimed to transform the Soviet economy from a peasant society into an industrial superpower. These policies involved forced collectivization of agriculture and the seizure of privately-owned farmland and livestock. The grain was sold on foreign markets to generate cash to aid in the Soviet economy's re-shifting.
However, these actions resulted in a massive famine, known as Holodomor or the Ukrainian Genocide, resulting in the death of an estimated 7,000,000 people in Ukraine, known as the breadbasket of Europe. The policies that led to this tragedy included demanding high quotas of grain before feeding the populace, resulting in widespread starvation when these quotas could not be met.
Hence, Option C is correct.
