In context, which is the best way to revise sentence 6 (reproduced below)? (6) This is also true of the sculpture of Degas, who was known as a painter rather than a sculptor, and whose sculpture also was not widely exhibited at the time.
Delete the words ", and whose sculpture was also not widely exhibited at the time."
Since the sentence begins with "This is also true," the phrase in this choice is redundant with the preceding sentence. None of the other choices address this.
