Dr. King uses the words "heat of injustice” and "heat of oppression” to describe Mississippi because
A)he is describing a very warm climate.
B)it is full of uncomfortable racism.
C)it is the only state with inequality.
D)he is persuading people to move away.
I believe the answer is B) because he is saying "heat" in a way to describe something that is very active and occurring. It is a very hot, or popular, thing.
(Almost as if he is saying racism is hot and in its prime.)
