Multiple files for the same movie. Which one will played by default?

Let's imagine that I have a movie in different qualities:

• 4K MicroUHD, 
  
• 1080p BD-Remux
  
•  1080p Micro-HD
  

Which file will be the one played by default and how will Jellyfin decide that?

I would imagine it's would be in alpha-numeric order. I don't have access to my jellyfin to double check. I have a movie that has a "Black and White" and "Colorized" version and I think B&W is select by default.

I will double check when I can access my jellyfin.
