The option which is an example of the weakest research question is A. What type of flower grows best in a Pacific Northwest garden?
This is because here, you are just going to say what flower that is, and maybe say a few words about it, and that's it - there's no actual research to be conducted here. The other options are far more extensive, and you can actually write about them a lot.
