This answer should be A !
Hello there! :) I provided info for you below, hope it helps.
SO basically...Running water on the surface of the earth erodes the land. Groundwater also can cause erosion under the surface. As water flows through the soil, acid is formed. This acid can cause minerals to be dissolved.

Minerals that are carried in groundwater can also be deposited in other places. This cycle of erosion and deposition can cause underground caves to form. This happens especially in areas where there is limestone below the surface.
A cave is an underground opening. It has a connection to the surface of the earth. A cave is formed by the erosion of limestone under the ground. The acid water moves through the cracks in the limestone and makes them larger.
So the first one provided will be your answer! :3 <3
Answer:
I think water does follow the law of conservation because water gets heavy every time like a Hurricane or a Tsumani they're both made out of the water and they do a lot of damage like Hurricane Delta was the record-tying fourth named storm of 2020 to strike Louisiana, as well as the record-breaking tenth named storm to strike the United States in that year.
