Lincoln say about popular sovereignty that when self-government was used to rule other people, it was tyranny.
Answer: Option A
Step-by-step explanation:
The fundamental truth on which the state's authority and its government generated and sustained by people is “Popular Sovereignty”. Lincoln said that this principle can nationalize and perpetuate slavery because when white man rules himself then it is self government.
But when he rule or governs another man too than it becomes tyranny and named the phenomenon as despotism. The extension of slavery to the state was intensely criticized by him under the supposed doctrine of “self-government”.
