What's a cone of depression?

a. an area where surface water reaches an aquifer
b. an area where a cave collapses in on itself
c. an area where the water table slopes toward a well
d. an area where one cave connects to another cave

I believe that it is C. An area where the water table slopes toward a well.

Explanation:

C. An area where the water table slopes toward a well

depressed springs will form if the groundwater level is cut by topography. Spring water is a producer of clean water that people commonly use for various purposes of life. Water that comes from springs is usually water that is suitable for consumption because it has experienced purification (self purification). One of the areas that have the potential of large springs is the volcanic slope area. In young Strato volcanoes, generally have a spreading pattern of springs that surround the body of the volcano to form a belt-like pattern, commonly called a spring belt. This is a symptom of the appearance of a typical spring and is common in strato volcanoes in Indonesia, especially in Java. At certain heights there are spring belts that are related to their orohydrological properties, also related to slope changes caused by changes in the structure of their rock. Volcanic activity in the Depression Zone filled with young volcanic deposits generally produces rocks composed of andesite to basalt, both in the form of loose rocks in the form of fine-grained to coarse (pyroclastic) volcanoes, and solid rocks in the form of streams and lava domes. The deposition of material ultimately forms aquifers that have high porosity and permeability, especially in the morphology of volcanic slopes to fluviovulic plains. This is further supported by the presence of rainfall falling on a fairly high landscape. The distribution of springs with various flow discharges is found in the body of the middle volcano (volcanic slope) to the bottom (volcanic foot), with the place of appearance more or less in accordance with the place of change in the slope of the slope (break of slope), which indicates changes in the level of rock graduation.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
