What is the correct sample?

Android Tests. You can use the childSelector() method to nest multiple UiSelector instances. For example, the following code example shows how your test might specify a search to find the first ListView in the currently displayed UI, then search within that ListView to find a UI element with the text property Apps.

What is the correct sample?
A . val appItem: UiObject = device.findObject( UiSelector().className(ListView.class)
.instance(1)
.childSelector(
UiSelector().text("Apps")
)
)
B . val appItem: UiObject = device.findObject( UiSelector().className("android.widget.ListView") .instance(0)
.childSelector(
UiSelector().text("Apps")
)
)
C . val appItem: UiObject = device.findObject( UiSelector().className("android.widget.ListView") .instance(
UiSelector().text("Apps")
)
)
