What russian leader was known for opposing a coup in the soviet union from a tank

Are there any answer choices?

Cause I believe it is Boris Yeltsin

I hope this helps!

Boris Nikolayevich Yeltsin was president of the Russian Federation, a position he held between 1991 and 1999. On July 11, 1990, during the celebration of the XXVIII Congress of the Communist Party of the Soviet Union, Boris Yeltsin announced his resignation in the CPSU. In the presidential elections of June 1991, Boris Yeltsin, standing as an independent, was elected president of the Soviet Federative Socialist Republic of Russia with 57% of the votes.

He was re-elected in 1996, defeating Gennady Zyuganov of the revived Communist Party. However, Yeltsin never regained his initial popularity after a series of economic and political crises in Russia during the 1990s.

In August 1991, Yeltsin won international applause by promoting himself as a democrat and by challenging the August 1991 coup attempt carried out by hard-line communists in the Soviet government and in the KGB. After the dissolution of the Soviet Union in December 1991, Yeltsin undertook to transform Russia's socialist economy into a free market economy and implemented economic shock therapy, liberalization of prices and privatization programs. Due to the privatization method, a large part of the national wealth fell into the hands of a small group of oligarchs.
