The correct answer is B) To separate Jewish from non-Jewish prisoners in concentration camps.
The yellow triangle described in the question represents the Star of David. This is an important symbol for individuals who practice Judaism. The Nazi's used this to distinguish between the different types or prisoners at their concentration camps during World War II. This is due to the fact that the leader of the Nazi Party, Adolph Hitler, constantly blamed Jewish people for the problems faced by the German citizens after World War I.
