Answer:
B). They are both meant to preserve segregation.
Step-by-step explanation:
Martin Luther King, Jr. was deeply concerned about the injustices held upon the black community. In his 'Letter from Birmingham City Jail', he addresses the actions of police against the black people primarily meant to 'encourage segregation.' He links the public as well as private actions of the police like 'leaving angry violent dogs to bite non-violent Negroes, pushing and cursing the old black women and young girls along with the slaps and kicks to black boys and old men, even denying them food' to highlight the unfair and unjustified treatment to the black community. It clearly implies that they(police) were promoting the preservation of segregation between the black and white communities. Thus, option B is the correct answer.
