Question

after lenins death in 1924, the soviet union was supposed to be led by a troika which is a general assembly group of three dictator king

Explanation:

The term "troika" in Russian means a group of three. In the context of Soviet history after Lenin's death, the troika was a group of three leaders (Stalin, Zinoviev, and Kamenev) supposed to lead. "General assembly" is not specific to a group of three, "dictator" is a single ruler, and the Soviet Union was not led by a king. So the correct meaning of troika here is a group of three.

Answer:

B. group of three
