Answer: D

NEW QUESTION # 145
A page loads 50+ < div class= " ad-library-item " > elements, all ads.
Developer wants to quickly and temporarily remove them.
Options:

A. Use the DOM inspector to prevent the load event from firing.
B. Use the DOM inspector to remove all elements containing the class ad-library-item.
C. Use the browser console to execute a script that prevents the load event from firing.
D. Use the browser console to execute a script that removes all elements containing the class ad-library- item.

Answer: D

Explanation:
The goal:
" Temporarily and quickly remove them. "
The fastest way is to run a script in the browser console that removes all such elements:
document.querySelectorAll( ' .ad-library-item ' ).forEach(el = > el.remove()); This immediately removes all 50+ elements and requires no page reload.
Option analysis:
* A & B : Preventing load events is unreliable and does not remove already-created DOM nodes.
* C : Correct-console code can remove all matching DOM elements instantly.
* D : Possible but extremely slow; removing 50+ elements one by one in the inspector is not "quick." Therefore, C is the best answer.
JavaScript Knowledge References (text-only)
* The browser console can run arbitrary JavaScript that manipulates the DOM.
* document.querySelectorAll() returns all matching DOM nodes.
* Nodes can be removed using .remove().
