Laminate flooring direction?
I’d replace the kitchen material or use a different material (like tile). If you must install similar material, I’d Install it in Direction “A”, because:

1) Installing material that is NOT identical in the same direction will look like a “mistake”. 

2) Material across a hall will look like scraps were used. 

3) Make a bold statement by using a different colored threshold material between the kitchen and living room.
