Explanation / Answer
1) all available choices are correct
large mass of water is locked as glacier or polar ice cap. So if a large of mass of ice caps melts, it could result into rising level of sea water.
sea floor spreading builds new ocean crust increasing the volume of the basin which can decrease the sea level
subsidence is the shrinking of land mass usually experienced in the coastal areas and the opposite of subsidence is uplift. Shrinking of land in the coastal region can cause changes in the sea level.
