I don't like the one with the squiggly lines. It doesn't seem like it fits.
The one with the straight lines is acceptable, if a little bland. Not sure why, but the squares did look better visually, even if they made less sense. I wonder if B with lines would look good or if it would also look bland.
If there's no other way to make it look interesting with the lines, the best options might either be to simply go with the squares instead of the lines or do a design like F that doesn't require either
