B)The water level will rise,but not as much as the 10% indicated in answer
C)The water level will remain unchanged.
D)The water level will become lower.

The water level remains unchanged because the volume of water displaced by the ice is equal to the volume of water the ice turns into when it melts. This is due to the principle of buoyancy and the fact that ice expands to occupy a larger volume than the water it was made from, which compensates for the part of the ice that floats above the water level.
