Onblur and onfocus are triggered when an element loses or gains focus. This makes them

• A. Global attributes
• B. Boolean attributes
• C. Event attributes
• D. Data attributes

Answer: (C)

Onfocus and onblur are event handler attributes in HTML. They specify JavaScript to run when the element gains or loses focus, respectively, making them examples of event attributes. This category is about attributes that react to user interactions or other events, instead of merely describing the element or storing data. They’re not global attributes (which apply to many elements), not boolean attributes (like disabled, checked), and not data attributes (data-* used for custom data). The key idea is that these attributes wire up code to respond to specific events, here the focus events. For example, you might use them to validate input when a user enters a field or to update styling when a field gains focus. In practice, you can also attach such behavior with addEventListener, but understanding that onfocus and onblur are event attributes helps you recognize how inline event handling is defined in HTML.
