Why did Jefferson refer to his election to presidency as the "Revolution of 1800"?
because there were many changes in the country at that time
because he believed that he would lead the people to revolt against unfair laws
because he believed the future of the Republic was at stake
because he believed that Adams would attempt to restore monarchy rule

The right answer is:

Because he believed that he would lead the people to revolt against unfair laws.

Explanation:

Very restrictive laws were passed by Congress during the presidency of John Adams in the last years of the 1790s decade. A war with France was seen as probable, so the Adams administration asked for harsh laws that created much disatisfaction among citizens. They were called the Allien and Sedition Acts. Their critics said they severely restricted civic freedoms and constitutional rights. With the public mood against the laws, Thomas Jefferson campaigned against them and won the presidency in 1800.
