The action that would be consistent with a person who believed in civil disobedience is:
a conductor on the Underground Railroad guiding escaped slaves.
Civil disobedience typically involves the active, professed refusal to obey certain laws or demands of a government or occupying international power, often in a peaceful manner. Guiding escaped slaves on the Underground Railroad is an example of this belief in action, as it was a direct violation of laws that upheld slavery.
