I dont believe "You Can See" is one. Just think of the question as this- "Based on the passage, why is genetically modified food safe?"
Choices that make sense were
more vitamin A
could help save
more nutritious
I also left out "unsubstantiated risks" because the definition of unsubstantiated is "Not supported or prooven by evidence". So "Unsubstantiated risks" means "un-prooven risks." this does not mean its safe.
