C and D are both wrong because `onload` and `onDOMContentLoaded` are not valid event listeners. You need to use the `addEventListener` method instead.

I'm going to go with option A. `window.addEventListener('load', personalizeWebsiteContent)` is the way to go. I mean, who wants to wait for all those resources to load before personalizing the website? Not me, that's for sure!

Option B is incorrect because `DOMContentLoaded` is triggered when the initial HTML document has been completely loaded and parsed, but before all the resources (such as stylesheets and images) have finished loading.

The correct answer is A. The `load` event is the correct one to use when you want to execute a script as soon as the page is loaded, regardless of when the external resources are available.

But wouldn't using 'load' ensure that the script is executed when all resources are loaded, providing a better user experience?
