The correct answer is D) Siberia.
Czar Nicholas I suspected dissenters in Siberia.
Czar Nicholas I (1796-1855), was an autocractic emperor of Russia. His government was based on the militia and bureaucracy. This generated corruption from the inside of his government. Nicholas I was affraid of the revolutionary movements in other countries of Europe and became isolated, reactive and protective of its territories. That was one of the reasons of the Crimea War against France, Sardinia, and England.
