I think options B and D are the correct ways to pass data from the parent to the child component. Using a public property or a custom event seems like the most straightforward approach.

I'm not sure about option C and D. Using the Apex controller class seems unnecessary for passing data, and custom events might be more suitable for other purposes.

I agree with Aleshia. Option B is also valid because using a public property is a common way to pass data between components.

I think option A is correct because the parent component can directly call a method in the child component.
