What is the correct cause of pillar formation in a karst cave?
Answer and explanation
Correct answer: Joining of stalactite and stalagmite
The governing concept is solution and deposition in limestone caves. Water containing dissolved carbon dioxide slowly dissolves limestone and later deposits calcium carbonate as it drips. A stalactite grows downward from the cave roof, while a stalagmite grows upward from the floor. If both formations meet, they create a continuous pillar or column. Therefore option B is correct; the other choices describe river, wind, or coastal processes.
