The correct answer is C. Vladimir Lenin and the communists overthrew the Russian tsar.

Explanation:

The Russian Revolution took place in 1917, when Vladimir I. Lenin and the Red Army faced and overthrew the tsar and the White Army.

B was a result of the reforms so it is also incorrect, while C is incorrect because Stalin ruled the USSR between 1922 and 1952, so his tenure started 5 years after the Revolution.
