For future who answer question and to who ever sees this. Can like not put like different answer like, it was A and was B and it was C. Like that is so frustrerating. please don't put oh because I took the test and got it correct because there's times were people get answers from this but not being specific will cause them to not believe your answer. Which will cause you to not get your points. So please be more specific and give correct answer. Thank You :)

As you sit in the library with your friend studying for your weekly quiz on the integumentary system, you come upon an article about the hazards of prolonged exposure to the sun's rays. your curious nature leads you to research the subject further. you're fascinated to learn that minimal exposure to the sun allows you skin to manufacture vitamin d, which is important to maintain homeostasis. you also read that although sunscreen can protect you from the ultraviolet (uv) rays of the sun, some medications can actually increase a person's sensitivity to the sunlight.
