c. organized farm workers into a powerful union.

Explanation:

Cesar Chavez was a Hispanic labor leader and civil rights activist whose work towards ensuring pay rise and improved working conditions among workers became one of the most significant changes for the Hispanics in American history. He was a huge supporter of the non-violent means of protest that was exemplified by Mahatma Gandhi and Martin Luther King.

One important fact about Chavez was that he helped organize farm workers into a powerful union, which then helped in the demands for better conditions for workers. He founded the National Farm Workers Association and became a prominent face for the protests against any injustice to the workers whose efforts to put food on the tables of American families often were neglected. And under his leadership and the growing of the labor union, Chavez helped in the demands for improved working conditions and higher wages for workers.

Thus, the correct answer is option c.
