"Stories have always been an important part of my life that have held immense fascination for me, starting from when I was just a child. When I was very young, my favorite fairy tale was Cinderella. I would ask my parents to read the story to me every night—and I always demanded that they use different voices for each character. Sometimes I would make up my own dialogue to supplement the story. When I got older, I even wrote my own stories. They were full of larger-than-life characters and magical events, just like the story of Cinderella. My dream is to one day work in the film industry bringing exciting stories to life."
The correct answer is A) I studied that when I was in sixth grade. In this independent sentence, the adverb clause is 'when I was in sixth grade'. An adverb clause is a subgroup of dependent clauses, meaning that it cannot exist on its own, outside of the main, independent clause. Just saying 'when I was in sixth grade' means nothing, it is incomplete.
Hope this helps :)
