Help me plsss which prompt would be best addressed with the cause-and-effect structure?

The best cause and effect structured prompt would be B.

Explanation:

Cause and effect is when one action leads to another or causes changes in something else. The civil rights movement of the 1950s led to historic changes in American laws. It changed our laws and that is cause and effect. Hope this helps :)
