Answer: Option (D)
Step-by-step explanation:
The above analogy (comparison) is given that , statues are made by curving them. Similarly, the caves are also formed from erosion of the rocks.
Caves are the erosional features that are formed due to the dissolution of limestone (undergoing chemical reaction with the ground water).
Caves are often characterized by the karst topography and stalagtitte and stalagmite are the two forms of mineral that occurs in a cave. Stalagtites are formed when the acidic water falls from the roof of the cave and are very pointed, whereas stalagmites are formed at the floor of the cave and have rounded tips. When both stalagtites and stalagmites are joined then its called pillar.
Thus, the correct answer is option (D).
