The correct answer is C) Mark explains that none of his friends have ever met anyone that has died from a smoking-related illness.
The scenario that is not a good example of using supporting materials is "Mark explains that none of his friends have ever met anyone that has died from a smoking-related illness."
When we are talking about supporting materials we refer to all those pieces of information and data that support our arguments. In the case of this question, Mark is only explaining without showing none evidence that supports what he is saying. Darek is quoting an important American Association. That supports his point. Jana is showing a powerpoint presentation, trying to show evidence of what she is saying.
