The Seattle Sit In demonstrated the effectiveness of A. Labor unions. B. Political speeches. C. Civil disobedience. D. Violent protests.

Option C

Explanation:

In the years 2020 and 2021, the city of Seattle was rocked by demonstrations over the assassination of George Floyd. Starting on May 29, 2020, protesters took to the sidewalks around the town for demonstrations as well as sit-ins, which were often nonviolent but also turned violent.

Civil disobedience can be understood as the citizen's active, public failure to follow a government's rules, requests, orders, or commands. To be considered "civil," civil resistance must be peaceful, according to certain meanings. As a result, civil activism is often confused with passive opposition or lawful demonstrations.
