The ocean level rises when global temperature rises, due to ____________________. A) Both of these.B) Neither of these.C) melting of ice caps at the poles.D) thermal expansion of water

1. 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.
