Correct answer would be A and D. Karst topography is the characteristics of limestone terrain forming various geomorphological structures by dissolution in the presence of underground water. Sinkholes are depressions caused due to dissolution of limestone and they grow in size persistently through solvent action. Dolines are also referred to as the collapse sinks. They are similar to the sinkhole in appearance but less common than sinkholes. Other two terms are related to groundwater geology. Clearly, Pumping from a well in a water table aquifer lowers the water table near the well and the area resulted is known as a cone of depression. The land area above a cone of depression is called the area of influence.
