By the early 1960s
a) blacks had reached equality with whites on most socio-economic measures
b) racial discrimination was still very much a part of american society
c) affirmative action policies had been in place for decades
d) the civil rights movement had achieved its most important goals

c

Explanation:

By the early 1960’s, racial discrimination was still very much a part of American society.

Option B

Explanation:

The civil right movement though achieved its most important in the 1960's but during the late of 1960's and some early of 1970's therefore the option D stands incorrect. The affirmative action policies were in place for decades but not on real ground therefore this option too stands incorrect.

And it much more time for the racial equality to come into play though have been in the motive of John f. Kennedy election campaign. The sit in movement and civil right movement were all seen during the early 1960's but discrimination was still present in the society. So, this looked as in very much role for the African Americans.

if you are going to ask a question give options..
