Answer:
A reason the Virginia and Kentucky resolutions were written in secret was that the authors' criticisms were illegal under the Sedition Act.
Step-by-step explanation:
The Virginia and Kentucky resolutions were numerous political statements that criticized and deemed the Alien and Sedition Acts adopted by the federal government as unconstitutional. These documents argued that the federal government has no right to interfere in the state laws.
One main reason these resolutions were written in secret was that the authors fear they might be charged with treason under the Sedition Act. Their criticism of the federal laws was illegal under the law and was capable of making them liable to be arrested under the Sedition Act.
Thus, the correct answer is the last option.
