Explanation:

Dr. Martin Luther King Jr. was a prominent civil rights leader who used non-violent methods to advocate for legal and social change. He delivered famous speeches (like "I Have a Dream") to rally support for equitable laws, and he also wrote books to outline his principles. Among the options, giving speeches is a well-documented, core action he took to push for legal change. He rejected violence, and "fight" is not associated with his non-violent approach.

give speeches
