Button. Content> tag in XAML is the syntax for ____________. Namespace Property Element Class Form

The correct answer is Property Element.

In XAML (Extensible Application Markup Language), the Content property of an element like a Button can be set using a property element syntax rather than just using attributes. This allows for more complex types of content to be placed within the button, such as multiple child elements or controls.

In this context, the Content> tag allows you to define the content that will be displayed within the Button, which could include text, images, or even other controls. Hence, the tag is specifically focused on defining the content area of the Button, making it a prime example of a property element.

In conclusion, the primary reason it is classified as a Property Element is due to its functionality in conveying what object or elements are nested within the Button control in a structured format.
