Which of the following terms is used to modify an HTML element?

Attributes are essential components of HTML that provide additional information about elements. They allow developers to modify the behavior and appearance of HTML elements by setting specific properties. For example, attributes can be used to define the source of an image, link a webpage, or specify the target of a hyperlink. Each attribute typically consists of a name and a value, which enhance the functionality of the HTML element to which they belong.

Tags, while crucial for defining the structure of the document, do not modify elements themselves; rather, they delineate the start and end of an HTML element. Classes are used primarily for styling and can group elements that share common styles, but they are not a direct modification mechanism by themselves. Styles refer more specifically to CSS rules applied to elements and may reside either inline, internally, or externally, but are not a term that fits the direct modification of the elements on its own.
