which logical layers should you assign the components?

DRAG DROP
You are planning the architecture of a new Windows Store style e-commerce app. You need
to maximize reusability by breaking app components into logical layers.
To which logical layers should you assign the components? (To answer, drag the
appropriate components to the correct layers in the answer area. Each component may be
