A puzzle for you - who is first?

When I was a kid, I loved logic puzzles. Here is an example. Try it out!

Ari, Bella, Claire, and Don are competing in a race. Who finishes first, second, third, and last?
​
Here are the clues:
If Ari doesn’t come in first and Bella doesn’t come in second, then Claire is third.
If Don does not finish last, then, if Ari is not second, Bella finishes third.
If neither Claire nor Don finishes second, then Bella is third.
At least one of the following is true: Claire finishes last, Don finishes first, or Ari finishes in third place.
