A. The murder of Emmett Till

Explanation:

Emmett Louis Till (1941–1955) was an African American boy lynched in Mississippi, with the excuse of having offended a white woman.  

The despicable cruelty of his murder and the later acquittal of his killers led thousands of people across the United States to pay attention and even dedicate themselves to the Civil Rights Movement, to which Till became a posthumous icon.
