Haha, option C is just silly. Who would even think of handling a 'lead' event? That's not a real thing!

I'm leaning towards option D. Handling the DOMContentLoaded event in the script itself seems like the most direct approach.

Yeah, I would go with option D as well. It's important to make sure the script runs when all the content is loaded.

I think option D is the best choice. Handling the DOMContentLoaded event directly in the script makes sense.

Hmm, I'm not sure. Option A seems like it could work too, since the requirement is to execute the script when the page is fully loaded.

I think option B is the way to go. It makes the most sense to handle the loading of the script directly within the script itself.

I agree, having the handler within the personalizeWebsiteContent script for the load event seems like the most efficient solution.
