Answer:
C. Justice and righteousness.
Step-by-step explanation:
In his "I Have A Dream" speech, Martin Luther King Jr. called for an end of racism in America and also for civil and economic rights for the African- Americans. It became a defining moment for the civil rights movement and also became one of the most iconic speeches in American history alongside Lincoln and Jefferson.
In his speech addressing the issue of racism and civil liberty, King mentions that there are some who still question when they (the civil rights devotees) will be satisfied, even with what the nation had done and already granted independence. But satisfaction will only be achieved when "justice rolls down like waters, and righteousness like a mighty stream". This speech delivered during the March on Washington for Jobs and Freedom on 28th August, 1963 brought about a major focus to the issues addressed and also cement the black people's dream of gaining their rights under the leadership of Mr. King.
