Is this a run on sentence if so which one

The second one. The first one has comas

The second one

Explanation:

The second one keeps RUNNING ON, that's why it's called a run-on sentence. The writer should've put a period, but they kept going on. Here's an example of a run-on sentence:

"We went to the grocery store and bought some bread, yogurt, and lettuce, and we then went to the library and then we went to our house and then we watched a movie and I loved it so much!"

Hope this helps! :)
