I'm not sure about this one. Isn't 'composed: true' the key to making the event cross the Shadow DOM boundary? I'll have to double-check the documentation on that.

I'm not sure, but I think composed: true is also needed to cross the Shadow DOM boundary.

Hmm, I think option C is the correct answer. The 'bubbles: true' property allows the event to bubble up the containment hierarchy, and 'composed: true' ensures the event can cross the Shadow DOM boundary.

I agree with Emogene, because setting bubbles to true allows the event to bubble up the containment hierarchy.
