Answer:
B. an image of Cesar Chavez leading a peaceful
march
Explanation:
Cesar Chavez was a civil rights activist and a leader of farm workers fighting for better working conditions. He is most famous for his work in the 60s and 70s when he organized strikes and boycotts against working conditions on farms and plantations.
He used direct, but non-violent means of fight, fighting only with peaceful protests, marches and boycotts until demands were granted.
So, the best illustration for this sentence would be an image of one such peaceful march led by Chavez.
Also, that is the only option that shows any mean of fight for better working conditions.
