A) The water table was much higher, and the increased water brought in extra material to form the decorations.
B) The water table was much lower, and the features were formed by water dripping from the ceiling into an air-filled chamber.
C) The water table has always been at that level and the cave decorations formed through the fracturing of the ceiling.
D) The water table has always been high, but molten material was able to extrude underwater.
