I was a bit surprsed to find the answer as (A). http://www.reuters.com/article/2012/02/08/us-climate-sealevels-idUSTRE8171RH20120208
Ice caps that are floating while melting do not raise the water level, but melting ice shelves and glaciers on land do raise the level. Thermal expansion throughut all the world's warming oceans also contributes significantly.
