Answer:
d. sa biographie
Step-by-step explanation:
The obvious thing is that Simone is a feminine name because it ends with an e, so you would use "her" or "sa", but for the sake of learning...
The text, when translated to English, means "If I want to know the life of Simone De Beauvoir, I can read...". Sa biographie means "her biography". A biography is a novel written about someone else's life, so if you want to know about the life of Simone De Beauvoir, it'd be in your best interest to read that.
Hope this helps! Happy learning :)
