The correct answer is A. Categorized button.
A categorized button is used to display the names in the property list by category. This means that the names will be grouped together based on their category. For example, all of the names that are related to “people” will be grouped together, and all of the names that are related to “places” will be grouped together. This can be helpful if you are trying to find a specific name or if you want to see all of the names in a particular category.
The other options are incorrect because they do not describe the function of a categorized button. A alphabetical button is used to display the names in the property list in alphabetical order. A lexicographical button is used to display the names in the property list in lexicographical order. A group button is used to group the names in the property list into groups.
