Android studio used to generate version 1 of apk, now it is 3. What does each of them do?

Question

So, I did not release this after a while. Android Studio is used to generate only one apk, which was the release version. This time it generated 3, as shown below:

1.app-armeabi-v7a-release.apk
2.app-x86-release.apk
3.app-universal-release.apk

I'm going to suggest that I want to use the universal one for the Google Play Store.
But can someone break the specifics of each of them?
