In the DOM, boolean attributes are represented as properties that can either evaluate to true or false. When a boolean attribute is present on an element, it is considered true, and when it is absent, it is false. This means that the browser treats these attributes as properties rather than text or objects.

For example, when using the `disabled` attribute on an input element, if the attribute is present, the value of the `disabled` property will be true. If it is not present, the property will report as false. This characteristic allows developers to easily check the state of the attribute using JavaScript, enhancing dynamic behavior in applications.

The other representations listed—numeric values, string values, and objects—do not accurately reflect how boolean attributes function within the DOM. Boolean attributes do not have a numeric or string representation; they simply toggle between the presence (true) and absence (false) in the DOM structure.
