Answer:
c is the correct option.
Step-by-step explanation:
When King was arrested in the 1960s for being with a group protesting the attempt to integrate the dining room of an Atlanta department store. The protesters were releases but King was the only one who was still in Jail for unrelated traffic charges. John F. Kennedy called the King's wife to express sympathy, but shortly after the called King was released from the jail. His release shifted the Black people's favor towards him and it also led to the shift of crucial votes in Northern states away from Nixon and making Kennedy's victory possible with a slight margin, which was due to the votes of the black. Despite all this, there is no clear evidence that King supported Kennedy in 1960's elections.
