An instructor is explaining the functions, sources, and intake recommendations for vitamins. The instructor realizes additional instruction is required when a student says:
A) "It is vital to consume an adequate amount of most vitamins in our daily diet or through supplements because the body cannot manufacture many of them."
B) "With exposure of the skin to sunlight 15 minutes twice per week, the body can synthesize a significant amount of the needed vitamin D."
C) "Fat-soluble vitamins serve as coenzymes for metabolism throughout the body and help to stimulate appetite, maintain healthy nervous and integumentary systems, and assist with growth."
D) "Because fat-soluble vitamins can be stored, they can become toxic when consumed in excessively large doses over a long period of time."
