Duct locations

Hi everyone. We recently moved into a house where the sun room isn't connected to our hvac. I'm looking to run some duct tomorrow to get some ac in there.

​The larger box in the image is the sun room. The smaller box on the bottom right is our entryway to the house, which is the only entry point into the sunroom.

Where would you suggest I place the duct(s)?
Is a return needed?
If yes, should it be in the sunroom or on the step riser of the entry way(E)?

Return not required if there's no door, or if you provide a transfer grille in the wall between the Sun Room and rest of house if there is. Supply outlet(s) should be at outside wall(s) away from the Sun Room entrance, especially if you're in a heating climate.
