Quizplus · Accepted Answer

The active ingredient in Retin-A, all-trans retinoic acid, is a form of vitamin A. Vitamin A is primarily obtained from fruits and vegetables, making choice A the best option. While vitamin A can also be found in meat and dairy products, Retin-A is not chemically related to these sources. Vitamin D, which is obtained from exposure to sunlight or through supplementation, is not chemically related to vitamin A or Retin-A. Vitamin K is produced by intestinal bacteria but is also not chemically related to vitamin A or Retin-A. Wheat is not a significant source of vitamin A.
