Best way to open a course using LMS

I built a course using Articulate tools and can publish it successfully. A sheet (content of all files) and the Zip version was generated. To this point, no problem !!! But for me, when I'm uploading the course on my LMS system, I can choose the way to open the Zip version.

I can choose 4 ways to configure how the course will start:
1. index_lms.html
2. index_lms_html5.html
3. Presentation.html
4. Presentation_html5.html

Please, what is the difference between these 4 options? Is there a better option?

Thanks in advance.
