What is true about this code snippet with alerts?

The correct answer indicates that only the first link will produce the alert "http://www.umich.edu/". This implies that the code snippet is set up in a manner where only the first link triggers the specified alert when clicked. This could be due to how event listeners are applied, the structure of the links, or specific conditions coded in the JavaScript related to the first link exclusively.

In web development, when dealing with links that contain event handlers, each link can have its own unique behavior based on how the JavaScript is structured. If the first link is set up with a click event that launches the alert, and the subsequent links do not have such an event tied to them, only the first will produce the alert specified.

The other choices suggest that either the second or third links or none of the links would trigger the alert, which suggests a misunderstanding of how JavaScript event handling or the link structure functions in this specific context. Therefore, understanding the relationship between event handling and the specific targets in JavaScript is crucial in determining which links produce alerts as intended.
