Answer:
B) Anti-black prejudice was basically a result of American slavery
Step-by-step explanation:
Anti-black prejudice in the USA is the result of years of slavery in that country. This is because, slavery placed blacks as people of low quality and who were not worthy of the best things, nor worthy of their own lives and were doomed to work excessively for the superior population, the whites.
When slavery was abolished, the feeling of superiority in many white citizens was maintained and perpetuated through the generations, making blacks still seen as inferior, unworthy, unclean and immoral, which created the racism present in society today.
