There are three possible answers to this question because there were (at least) three political parties that could be deemed "socialist revolutionaries.
First is the Bolshevik Party. Vladimir Lenin was the chief leader.
Second is the Menshevik faction of the Russian Social Democratic Labor Party. Julius Martov was the chief leader of that party.
Third is the Party of the Socialist Revolutionaries. Victor Chernov was the chief leader of that party.
Most likely this question refers to the Bolshevik Party under Vladimir Lenin, since it is the political party which overthrew the Russian Provisional Government (not the Tsar) in the October Revolution and later became the Communist Party.

Lenin was the leader and hero of the October Revolution of 1917, but had nothing to do with the February Revolution in 1917. Stalin was a subordinate to Lenin at the time so he was not a leader at all. Karl Marx had died by the time of the revolution, so aside from planting the ideas of socialism, communism and a revolt by the people in their minds, he had nothing to do with the revolution itself. well this is helpfull
