Answer:
D . experience
Step-by-step explanation:
When applying to a certain job, you want to show a future employer what you did beforehand and to prove to them you are worthy of the position. That is why you put examples of previous experiences that could be relevant.
If Tony is applying to work as a fashion photographer, he should list where he worked previously and put examples of his work in the experience section. This way the future employer can deduct from the work what Tony can do, what has he learned so far, and if his experience is good enough for the magazine.
