Answer:
d. Anonymous Black artists throughout history.
Step-by-step explanation:
Based on the excerpt provided in the question, the author wants to lay emphasis on the unknown identities of the various artists and workers who had to withhold their real identities for various reasons. These reasons may be for personal reasons, for their safety and also maybe due to their position in the society they are living in.
By the depiction of the generalized "anonymous black woman", the author is talking of all the unknown and even unacknowledged Black workers and artists throughout history and generations. Their works may have been discovered or not, but whatever the case, their works won't and can't be appreciated and applauded to them personally for they were "anonymous" to the world.
