Question 11

Identify the event handler which means that the user has made an object active.
A)onfocus

Therefore, this is the appropriate event handler for when a user makes an object active. The onclick event is triggered when a user clicks on an object, but this doesn't necessarily mean that the object is active. The onselect event is triggered when the user selects text within an object, and the onload event is triggered when a page or object finishes loading.
