Haha, using Apex to pass data between components? That's like using a sledgehammer to crack a nut!

I believe option D is also a valid way to pass data, using a custom event.

I like B and D too. Apex controllers are for server-side logic, not for passing data between components.

I agree with Tommy, using a public method seems like the most straightforward approach.

B and D are the way to go. Using public properties and custom events are the standard ways to pass data between parent and child components.
