Hello. You did not inform the text to which this question refers, but in the context of the question, we can consider that Pitts believes that it is important that children visit the "battleground" of the civil rights movement, so that they understand the rights that they possess have been conquered by many struggles and a lot of effort.
As the question refers to civil rights, we can understand that when Pitts refers to "children" he is referring to the African-American population that is young and was born in a world where their civil rights are guaranteed. In this case, it is important that this population visit the "battleground" of the civil rights movement, that is, visit the places where the protests and the claims of the African American population for their rights occurred. When visiting these places, the "children" of this population will understand that their freedoms and rights were obtained through much struggle and perseverance.
The answer is B. You're welcome.
