“Who is”
Hello.
Which sentence is right? “From what we have seen in the books about slavery of the time, it is ambiguous to discuss who IS this individual who deserves to be free” or ”From what we have seen in the books about slavery of the time, it is ambiguous to discuss who this individual IS who deserves to be free”? or even “From what we have seen in the books about slavery of the time, it is ambiguous to discuss who this individual who deserves to be free IS”?
Thank you
