Excerpt: we are confronted primarily with a moral issue. it is as old as the scriptures and as clear as the american constitution. the heart of the question is whether all americans are to be afforded equal rights and equal opportunities. are we to say to the world, and much more importantly, to each other, that this is a land of the free, except for the negroes, that we have no second-class citizens, except negroes, that we have no class or caste system, no ghettoes, no master race except with respect to negroes? now the time has come for this nation to fulfill its promise.

also judging from the diction in the above excerpt, what is the implicit meaning kennedy is conveying?
a.)it’s time for african-americans to rise up and fight for their rights.
b.)it’s time for slavery to be abolished
c.)america has so far failed to live up to the full promise of freedom and equal rights for all.
d.)since it is primarily a moral issue, there's no right or wrong answer
