Exam Associate Android Developer topic 1 question 64 discussion

In our TeaViewModel class, that extends ViewModel, we have such method: public LiveData<Tea> getTea() { return mTea;
}
An observer in our Activity (type of mViewModel variable in example is TeaViewModel) is set in this way: mViewModel.getTea().observe(this, this::displayTea);
What will be a correct displayTea method definition?
