The correct answer is option 2, which states that statement 2 only is correct.

To understand why, let`s analyze each statement individually:

Statement 1 claims that Mikhail Gorbachev was the first President of the Russian Federation. However, this is incorrect. Mikhail Gorbachev served as the General Secretary of the Communist Party of the Soviet Union and the last leader of the Soviet Union, but he was not the president of the Russian Federation. The first president of the Russian Federation was Boris Yeltsin, who served from 1991 to 1999.

Statement 2 states that Dmitry Medvedev is the fifth President of the Russian Federation. This statement is correct. Dmitry Medvedev served as the president of Russia from 2008 to 2012. He was the third person to hold the position of the president of the Russian Federation since its establishment in 1991.

Therefore, only statement 2 is correct, and the answer is option 2.
