yeah knifemissile, i'm with you.

the only way that the answer would be other than B is if the ice were really really big and hollow and holding a significant quantity of heavy gas or something. or if you're talking about a situation where the cup sides are not perfectly vertical and the cup is bearing some of the downward force of the ice cubes instead of the water. (actually, since the problem says that the pitcher is filled to the brim, the issue is if the pitcher is concave and the pitcher is bearing some of the *upward* force of the ice cubes trying to float.) the density of ice does not come into play at all, just as long as it's less than the density of water (so that it can float).

knifemissile explained it well. i have nothing more to add other than sapper, you really need to work on seeing the difference between negligible and significant factors in a given situation.
