Instead of a troika coming to power after Lenin’s death in 1924, what happened?

After Lenin died in 1924, no troika (a shared leadership) took lasting control. Stalin and Trotsky struggled for power, and Stalin gradually outmaneuvered Trotsky and secured leadership of the Soviet Union. Trotsky lost the struggle and was eventually exiled, so the correct choice is “There was a power struggle between Stalin and Trotsky, and Stalin won.”
