I almost got tripped up by option A, but then I realized that the classes property is not a method, so you can't use push() on it. These questions really make you think!

Ha! Option D is just plain silly. You can't use querySelectorAll() to add a class to a single element. I'm glad I didn't fall for that one.

Wow, these questions are getting trickier. I almost went with option B, but then I remembered that it's getElementById, not queryElementById.

Option C is the correct answer. The querySelector() method selects the first element that matches the specified CSS selector, and the classList.add() method adds the specified CSS class to the element.

I'm not sure, but I think D is incorrect because querySelectorAll returns a NodeList, not a single element.

I agree with Margarita. C seems like the correct option based on the syntax.

I think the answer is C because classList.add is used to add a class to an element.
