Apple ARKit is the only supporter of Human Body Tracking currently. As for how the selection is made, the underlying platform API (Apple ARKit) is the one that makes the decision on which body to track which is an opaque decision to AR Foundation.

If you want broaden your understanding, more details are provided in the following WWDC Conference Discussion: https://developer.apple.com/videos/play/wwdc2019/607
