B, on one of my rental homes I solved the problem by cutting a 1/4 inch piece of plywood the same size as the metal frame of the fan which is mounted in the ceiling in a hallway. I then fastened it with sheetmetal screws to the frame on the hall ceiling, painted it white like the ceiling and it looks great.
