Which one of the following statements is correct?
a. sea level drops when water is released from ice sheets and continental glaciers.
b. sea level drops when water is added to the oceans through increased rainfall and increased inflow from rivers.
c. sea level drops when evaporation rates increase over the oceans and when this extra, atmospheric moisture falls on land as rain.
d. sea level drops when water is stored in expanding ice sheets and continental glaciers.

D. Sea level drops when water is stored in expanding ice sheets and continental glaciers.

Explanation:

One of the most important and influential factors in the change in sea level is the change in the amount of ice that covers the Earth. This is because much of the planet's fresh water is stored in glaciers and ice sheets.

Then, the more water exists in solid state in glaciers and ice sheets, the lower the sea level. However, today the opposite is happening, due to the accelerated climate change, which has caused the melting of glaciers and sea level rise.

c, this answer is productivity.
