b. id for tv_label
c. iv_icond. tv_label

Answer 1

In an Android Studio project's List View item XML, the delete button ('btn_ del_ item') is optional, while identifiers for items and views for content such as icons and labels are typically required.

Step-by-step explanation:

The question is asking which item in a ListView item XML file for an Android Studio project is optional. In an XML layout for an Android application, the options are: btn_del_item: likely a button used for deleting items from the list. id for tv_label: the identifier for a TextView which displays text. iv_icon: the ImageView which might display an image. tv_label: another TextView for showing text, perhaps the season's name.

Out of these, the btn_ del_ item (button) is optional because an item identifier such as id for tv_ label, views for content such as iv _icon, and tv_ label are generally necessary for a List View to function correctly and to populate items with data. However, the delete button is a feature-related element and is not strictly required for the List View to present information.
