There will be a WC, basin and shower. I'm looking for a modern, preferably lots of white and some black in the design.

I would seriously consider replacing the cabinets before putting a new granite countertop on them. The problem is that no one will remove the countertop at a later date if you want to change the cabinets, due to the possibility of breakage. The only choice you will have then is a reface. Adding new doors, drawer fronts, and veneered sides is just a facelift. You could also add new hardwood drawers with undermount cushion close slides, but by the time you do this if will be the same cost as new cabinets now. The cabinets you have now, frameless, particle board sides are notorious for having the hinge screws strip out the particle board they are attached to. Since you can't put a longer screw in them, because the material is only 3/4" of an inch thick you have a problem. You also can't put a wider screw in them because it won't fit through the pre-drilled holes in the hinges.

Don't know about ABET laminates, but grew up with laminate countertop from a different mfg. No problems. We never placed anything hot directly on them, always used hot plates. But then again, i would never place anything hot directly on a granite counter. To nice looking...why take the chance ?

I vote A! What did you decide to do?
