Yep I also vote for B. I know its crappy having to open and redo but I think you will be happier with it in the long run.
But there is an option D: if you have the fabric, make 2 more blocks. Then you could take off one row and add a full row of 6 blocks to the width, giving you a quilt that is 45x56.
