Which Floor?

We're going for Pottery Barn appeal.  Our big room has a warm beigey white color (antique white, I think) as the walls and crisp linen white as the trim (the trim appears white white next to the walls).  We've painted the base of the island, the base of the computer cabinet and the window seat black (cushion is gone).  All the green trim is gone (all white now).  The cabinets are still the stained knotty pine with white knobs.  The island top is still oak, computer desk top still walnut.

Question:  Which floor color?  We're just trying to choose the best looking of the cheap options, not the most phenomenal of all the options.

A) American Classic Oak

 

B) American Cherry

 

C) Medway Park Merbau

D) Slatten

P.S.  I think we're going to get a little 4-6 seat dinette from Ikea that looks like this for a steal, and use a sisal area rug under it and another for the couch area.
