"Irish Nell Told [His Mother] the Day She Expected to Be

"Irish Nell told [his mother] the day she expected to be married,she was early up intending to clear the house out,and a Gentleman ...asked her if she was the Girl that was to be married that day to the negro? She said Yes,he then chid her,and told her,she would put a mark by that upon her Children and bring them into Slavery,that if she would marry a white man her Children might be of Credit in the world,otherwise they wou'd be in Slavery,upon which she fell a crying,and said it was to her Choice,she wou'd rather have Charles than have your Lordship." Why did the witnesses' testimony in "Analyzing Historical Evidence: Enslavement by Marriage" accuse Irish Nell of putting "a mark ...upon her Children?"

A) Because she married an African,her free white children from her first marriage had to become slaves.
B) Because she married an African,all of her future descendants would be slaves.
C) Because she had a child out of wedlock,she subjected this child to public shame.
D) Because she wanted to marry unencumbered,she sold her own children into slavery.
