The correct answer is C) she exercises freedom of economic choice.
Gabrielle's economic decisions best relate to broad economic goals in that she exercises freedom of economic choice.
Gabrielle has freely decided that she doesn't want to be engaged in a common 8-hour daily job. She has exercised freedom of economic choice. She opted for a combination of activities that satisfies herself. Part of the day in artistic projects and a job as a restaurant server in the evenings. This gives Gabrielle the money to dedicate part of her time to do what she likes and enjoys, that is art.
