Answer:
A) the black power movement.
Step-by-step explanation:
Many whites refused to support the civil rights movement, movements that sought equality and justice for African-Americans, out of fear for the inertia and strength that all the various black power social movements in the USA garnished during the sixties and beyond, making black power movements a political power to be reckoned with: this certainly frightened most conservative whites in fear that their own privileges could be lost when in reality all they lost was the unique opportunity to make their society a more just society.
