Answer
Answer:
Olaudah Equiano wrote a book, which was about his experiences as a slave and, later, as a free man.
Brief Explanation:
The relative - pronoun "which" correctly links the two ideas, indicating that the book is about his experiences. The other options use inappropriate conjunctions like "even if", "until", and "although" which distort the meaning.
