Wait, can events really cross the Shadow DOM? That's wild!

No way, I thought composed had to be false for it to bubble!

I thought it was A) at first, but C makes more sense.

Bubbles and composed both need to be true for that!

I keep mixing up the definitions, but I think D is wrong because it doesn't allow bubbling. I should have reviewed this more before the exam!

I practiced a similar question, and I remember that composed needs to be true for the event to cross the Shadow DOM. So, I think C is definitely a strong candidate.

I'm not entirely sure, but I feel like option A could be right since it allows bubbling, but I'm confused about the composed part.

I think the answer might be C because I remember that for an event to bubble and cross the Shadow DOM, both properties need to be true.
