Which Soviet physicist was known for civil liberties advocacy and human rights reforms?

• A. Dmitri Mendeleev
• B. Andrei Sakharov
• C. Yuri Gagarin
• D. Gregor Mendel

Answer: (B)

This question tests recognizing a Soviet physicist who became a prominent advocate for civil liberties and human rights. The person who fits this description is Andrei Sakharov. While he contributed to nuclear weapons science, he also spoke out against political repression and called for reforms, using his scientific prominence to argue for openness, freedom of expression, and the rights of individuals. He wrote influential essays and became a leading dissident, enduring government pushback that included internal exile; his international profile grew when he was awarded the Nobel Peace Prize in 1975. The other names are known for achievements in chemistry, spaceflight, and biology, not for civil liberties advocacy in the Soviet era. Therefore, the best answer is Andrei Sakharov.
